Asymmetric allylboration of 2-N,3-O-isopropylidene-N-Boc-L-serinal: Diastereoselective synthesis of the calicheamicin gamma1(I) amino sugar

Syntheses of the calicheamicin amino sugar 6 and its erythro diastereomer 7 have been completed by a sequence involving the asymmetric allylboration of N-Boc-serinal acetonide L-8 with the tartrate ester modified allylboronates (R,R)-9 and (S,S)-9, respectively. The reaction of (R,R)-9 and L-8 in toluene provides 14 with 89:11 selectivity, whereas the reaction of (S,S)-9 with L-8 in Et2O provides the diastereomer 15 with 90:10 selectivity. It is shown that the relatively modest diastereoselectivity of these double asymmetric reactions is compromised by the low enantiomeric purity of 8 (86-87% ee), and data are provided indicating that these reactions should be highly diastereoselective (?95:5 in each case) if performed with enantiomerically pure aldehyde. The two diastereomeric homoallylic alcohols, 14 and 15, are easily elaborated into the targeted amino sugars 6 and 7 via the acetamide-substituted pyranosides 22 and 26. Methyl pyranosides 22a and 22e were shown to adopt preferentially the unexpected conformations B and D, with axial acetamide substituents, in nonpolar solvents, while the expected conformations A and C were strongly favored in d6-DMSO because of hydrogen bonding interactions with the solvent. The syntheses of 6 and 7 reported herein are expected to facilitate the design and synthesis of analogs of the calicheamicin aryl tetrasaccharide 3, which should prove useful in further analysis and applications of oligosaccharides as DNA binders.

Synthesis of new trans double-bond sphingolipid analogues: Delta4,6 and Delta6 ceramides

Unsaturation was introduced at Delta4,6 and Delta6 of the sphingoid chain of naturally occurring ceramide 1 via a beta-keto sulfoxide (12) and sulfone (18) derived from N-Boc-L-serine methyl ester acetonide (9), affording two novel ceramide analogues, (2S,3R)-2-octanoylamidooctadeca-(4E,6E)-diene-1,3diol (2) and (2S,3R)-2-octanoylamidooctadec-(6E)-ene-1,3-diol (3). After C-alkylation of 12 with (E)1-bromo-2-tetradecene (8), a trans double bond was installed by elimination of PhS(O)H, providing conjugated dienone oxazolidine 13. Reaction of 18 with 8, followed by desulfonation (Al(Hg)), afforded keto-oxazolidine 20, which bears a (E)-Delta6 double bond. The syntheses of analogues 2 and 3 from ketones 13 and 20, respectively, were completed by the following sequence of reactions: diastereoselective reduction (NaBH4/CeCl3 or DIBAL-H), hydrolysis of the oxazolidine ring, liberation of the amino group, and installation of the N-amide group.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 95715-86-9 is helpful to your research. Reference of 95715-86-9

IOOC route to substituted chiral pyrrolidines. Potential glycosidase inhibitors

Branched-chain five-membered ring aza-sugar analogues, synthesized from amino acids by an intramolecular oxime-olefin cycloaddition reaction, the IOOC route, were found to be selective glycosidase inhibitors. The derivative 2,4(S)-di(hydroxymethyl)-3(S)-aminopyrrolidine, obtained from D-serine, was about 1 order of potency more active than its enantiomer obtained from L- serine.

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.category: oxazolidine, you can also check out more blogs about95715-86-9

Synthesis and structure-activity relationships of long-acting beta2 adrenergic receptor agonists incorporating arylsulfonamide groups

A series of saligenin alkoxyalkylphenylsulfonamide beta2 adrenoceptor agonists were prepared by reacting a protected saligenin oxazolidinone with alkynyloxyalkyl bromides, followed by Sonogashira reaction, hydrogenation, and deprotection. The meta-substituted primary sulfonamide was more potent than the paraand the ortho-analogues. Primary sulfonamides were more potent than the secondary and tertiary analogues. The onset and duration of action in vitro of selected compounds was assessed on isolated superfused guinea pig trachea. Sulfonamide 29b had the best profile of potency, selectivity, onset, and duration of action on both guinea pig trachea and human bronchus. Furthermore, 29b was found to have low oral bioavailability in rat and dog and also to have long duration of action in an in vivo model of bronchodilation. Crystalline salts of 29b were identified that had suitable properties for inhaled administration. A proposed binding mode for 29b to the beta2-receptor is presented.

(Chemical Equation Presented) A concise stereoselective approach to both orthogonally protected (25,4A)- and (2S,4S)-4-hydroxyornithine, key constituents of the biphenomycin-and clavalanine-type antibiotics, respectively, has been developed. The approach is based on bis(oxazoline) copper(II)-complex-catalyzed diastereoselective Henry reactions of nitromethane with the homoserine-derived aldehyde 6. The synthesis of this versatile chiral building block has been markedly improved.

Rational Design of Thermodynamic and Kinetic Binding Profiles by Optimizing Surface Water Networks Coating Protein-Bound Ligands

A previously studied congeneric series of thermolysin inhibitors addressing the solvent-accessible S2? pocket with different hydrophobic substituents showed modulations of the surface water layers coating the protein-bound inhibitors. Increasing stabilization of water molecules resulted in an enthalpically more favorable binding signature, overall enhancing affinity. Based on this observation, we optimized the series by designing tailored P2? substituents to improve and further stabilize the surface water network. MD simulations were applied to predict the putative water pattern around the bound ligands. Subsequently, the inhibitors were synthesized and characterized by high-resolution crystallography, microcalorimetry, and surface plasmon resonance. One of the designed inhibitors established the most pronounced water network of all inhibitors tested so far, composed of several fused water polygons, and showed 50-fold affinity enhancement with respect to the original methylated parent ligand. Notably, the inhibitor forming the most perfect water network also showed significantly prolonged residence time compared to the other tested inhibitors.
