Stereoselective synthesis of alpha,alpha?-substituted medium-sized cyclic ethers has been achieved by means of nucleophilic substitution of the corresponding lactone-derived thioacetals and their sulfone counterparts. Nucleophilic substitution of medium-sized lactone-derived thioacetals could be achieved efficiently either by (i) activation with NIS/TMSOTf in the presence of allyltrimethylsilane or TMSCN or by (ii) oxidation to the corresponding sulfones followed by treatment with an appropriate organometallic species such as divinylzinc or dimethyl(2-phenylethynyl)aluminum. Interestingly, the stereochemical consequence was found to be largely dependent on the local structure of substrates. In some cases, the gauche steric interaction developed in the transition state was considered to be responsible for the observed diastereoselectivity. The present method enables an efficient synthesis of a variety of alpha,alpha?-substituted seven- to nine-membered cyclic ethers from readily accessible lactone precursors.

Mycobactins are small-molecule iron chelators (siderophores) produced by Mycobacterium tuberculosis (Mtb) for iron mobilization. The bifunctional salicylate synthase MbtI catalyzes the first step of mycobactin biosynthesis through the conversion of the primary metabolite chorismate into salicylic acid via isochorismate. We report the design, synthesis, and biochemical evaluation of an inhibitor based on the putative transition state (TS) for the isochorismatase partial reaction of MbtI. The inhibitor mimics the hypothesized charge buildup at C-4 of chorismate in the TS as well as C-O bond formation at C-6. Another important design element of the inhibitor is replacement of the labile pyruvate side chain in chorismate with a stable C-linked propionate isostere. We developed a stereocontrolled synthesis of the highly functionalized cyclohexene inhibitor that features an asymmetric aldol reaction using a titanium enolate, diastereoselective Grignard addition to a tert-butanesulfinyl aldimine, and ring closing olefin metathesis as key steps.

The structural basis for antigen presentation by class II major histocompatibility complex (MHC) proteins to CD4+ T-cells is important for understanding and possibly treating autoimmune diseases. In the work described in this paper, (E)-alkene and ethylene amide-bond isosteres were used to investigate the effect of removing hydrogen-bonding possibilities from the CII259-270 glycopeptide, which is bound by the arthritis-associated murine Aq class II MHC protein. The isostere-modified glycopeptides showed varying and unexpectedly large losses of Aq binding that could be linked to the dynamics of the system. Molecular dynamics (MD) simulations revealed that the backbone of CII259-270 and the Aq protein are able to form up to 11 hydrogen bonds, but fewer than this number are present at any one time. Most of the strong hydrogen-bond interactions were formed by the N-terminal part of the glycopeptide, i.e., in the region where the isosteric replacements were made. The structural dynamics also revealed that hydrogen bonds were strongly coupled to each other; the loss of one hydrogen-bond interaction had a profound effect on the entire hydrogen-bonding network. The Aq binding data revealed that an ethylene isostere glycopeptide unexpectedly bound more strongly to Aq than the corresponding (E)-alkene, which is in contrast to the trend observed for the other isosteres. Analysis of the MD trajectories revealed that the complex conformation of this ethylene isostere was structurally different and had an altered molecular interaction pattern compared to the other Aq/glycopeptide complexes. The introduced amide-bond isosteres also affected the interactions of the glycopeptide/Aq complexes with T-cell receptors. The dynamic variation of the patterns and strengths of the hydrogen-bond interactions in the class II MHC system is of critical importance for the class II MHC/peptide/TCR signaling system.

(Chemical Equation Presented) A de novo preparation of alpha-keto-imides via ynamide oxidation is described. With a number of alkyne oxidation conditions screened, a highly efficient RuO2-NaIO4 mediated oxidation and a DMDO oxidation have been identified to tolerate a wide range of ynamide types. In addition to accessing a wide variety of alpha-keto-imides, the RuO2-NaIO4 protocol provides a novel entry to the vicinal tricarbonyl motif via oxidation of push-pull ynamides, and imido acylsilanes from silyl-substituted ynamides. Chemoselective oxidation of ynamides containing olefins can be achieved by using DMDO, while the RuO 2-NaIO4 protocol is not effective. These studies provide further support for the synthetic utility of ynamides.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Formula: C10H11NO2, you can also check out more blogs about102029-44-7

The serine/threonine kinase CK2 modulates the activity of more than 300 proteins and thus plays a crucial role in various physiological and pathophysiological processes including neurodegenerative disorders of the central nervous system and cancer. The enzymatic activity of CK2 is controlled by the equilibrium between the heterotetrameric holoenzyme CK2alpha2beta2 and its monomeric subunits CK2alpha and CK2beta. A series of analogues of W16 ((3aR,4S,10S,10aS)-4-{[(S)-4-benzyl-2-oxo-1,3-oxazolidin-3-yl]carbonyl}-10-(3,4,5-trimethoxyphenyl)-4,5,10,10a-tetrahydrofuro[3,4-b]carbazole-1,3(3aH)-dione ((+)-3 a)) was prepared in an one-pot, three-component Levy reaction. The stereochemistry of the tetracyclic compounds was analyzed. Additionally, the chemically labile anhydride structure of the furocarbazoles 3 was replaced by a more stable imide (9) and N-methylimide (10) substructure. The enantiomer (?)-3 a (Ki=4.9 muM) of the lead compound (+)-3 a (Ki=31 muM) showed a more than sixfold increased inhibition of the CK2alpha/CK2beta interaction (protein-protein interaction inhibition, PPII) in a microscale thermophoresis (MST) assay. However, (?)-3 a did not show an increased enzyme inhibition of the CK2alpha2beta2 holoenzyme, the CK2alpha subunit or the mutated CK2alpha? C336S subunit in the capillary electrophoresis assay. In the pyrrolocarbazole series, the imide (?)-9 a (Ki=3.6 muM) and the N-methylimide (+)-10 a (Ki=2.8 muM) represent the most promising inhibitors of the CK2alpha/CK2beta interaction. However, neither compound could inhibit enzymatic activity. Unexpectedly, the racemic tetracyclic pyrrolocarbazole (±)-12, with a carboxy moiety in the 4-position, displays the highest CK2alpha/CK2beta interaction inhibition (Ki=1.8 muM) of this series of compounds.

Cyclopropanes are commonly found in medicinal chemistry since they provide unique spatial and electronic features, combined with high metabolic stability in liver microsomes. Although many methods are found in the chemist’s arsenal to connect a cyclopropyl group to a carbon atom, none exist that perform the direct transfer of this useful fragment onto the nitrogen of a heterocycle or an amide. Considering the importance of nitrogenated compounds in the pharmaceutical industry, we sought to develop an expedient method to N-cyclopropylate azoles and amides. We report herein the direct cyclopropyl transfer reaction onto cyclic amides, isatins, oxindoles, imides, and carbamates employing a nonpyrophoric cyclopropylbismuth reagent. The reaction is catalyzed by copper acetate and proceeds smoothly in dichloromethane at 50 C in the presence of pyridine. The N-cyclopropylation reaction can also be applied to the preparation of N-cyclopropyl indoles, benzimidazoles, pyrroles, and pyrazoles. Copyright

Incubation of [2-2H]-(2S,3R)-2-methyl-3-hydroxypentanoyl-SACP ([2-2H]-1a) with the epimerizing ketoreductase domain EryKR1 in the presence of a catalytic amount NADP+ (0.05 equiv) resulted in time- and cofactor-dependent washout of deuterium from 1a, as a result of equilibrium isotope exchange of transiently generated [2-2H]-2-methyl-3- ketopentanoyl-ACP. Incubations of [2-2H]-(2S,3S)-2-methyl-3-hydroxy- pentanoyl-SACP with RifKR7 and with NysKR1 also resulted in time-dependent loss of deuterium. By contrast, incubations of [2-2H]-(2R,3S)-2-methyl-3- hydroxypentanoyl-SACP and [2-2H]-(2R,3R)-2-methyl-3-hydroxypentanoyl- SACP with the non-epimerizing ketoreductase domains EryKR6 and TylKR1, respectively, did not result in any significant washout of deuterium. The isotope exchange assay directly establishes that specific polyketide synthase ketoreductase domains also have an intrinsic epimerase activity, thus enabling mechanistic analysis of a key determinant of polyketide stereocomplexity.
