A general method for the synthesis of enantiomerically pure beta- substituted, beta-amino acids through alpha-substituted succinic acid derivatives

A general procedure for the synthesis of enantiopure beta-substituted, beta- amino acids is presented. Alkylation of the sodium enolates derived from chiral N-acyloxazolidinone imides 2 (R = Me, i-Pr, t-Bu, Ph, Bn) with tert- butyl bromoacetate afforded the 2-substituted succinate derivatives 3 in good yields (82-89%) and with high selectivity (? 93;7). Following hydrolysis, Curtius rearrangement of the resulting carboxylic acid provided the enantiopure benzyloxycarbonyl (Cbz)-protected beta-amino esters 6 in good yields (74-79%).

Inhibitors of the glycine transporter type-2 (GlyT-2): synthesis and biological activity of benzoylpiperidine derivatives.

A series of benzoylpiperidine analogs related to 4a was prepared, and their ability to inhibit the uptake of [(14)C]-glycine in COS7 cells transfected with human glycine transporter type-2 (GlyT-2) was evaluated. Small structural changes to the benzoylpiperidine region of the molecule led to a significant decrease in GlyT-2 inhibitory activity. In contrast, the distal aryl ring was more tolerant to functional group modifications and could accommodate a variety of substitutes at the C-2 or C-3 positions. Comparable activities to 4a were obtained by replacing the anilino nitrogen with an ether linkage 27 or by exchanging the isopropoxy ether moiety with an isopropyl amino group 15. A distinct preference for a 2-carbon tether (n=1) was observed relative to the corresponding 3-carbon homolog (n=2).

Useful synthetic method of polypeptides with well-defined structure by polymerization of activated urethane derivatives of alpha-amino acids

A facile polymerization strategy for synthesis of polypeptides with well-defined structure using urethane derivatives of alpha-amino acids in the presence of amine is reported. N-(phenoxycarbonyl) alpha-amino acid was polymerized at 60C in N,N-dimethyl acetamide (DMAc). The obtained polypeptides were adjusted by varying the initial ratio of urethane derivatives to amine, and the molecular weight distribution remained narrow (below 1.35). MALDI-TOF-MS revealed that the obtained polypeptides had amine-incorporated initiating end and amino group at propagating end without any side reactions, terminating chain growth. The block copolypeptides were established by polymerization of urethane derivatives in the presence of amine, followed by subsequent addition of other urethane derivatives. Copyright

Fluorine in fragrances: Exploring the difluoromethylene (CF2) group as a conformational constraint in macrocyclic musk lactones

The CF2 group is incorporated into specific positions within the lactone ring of the natural musk lactone, (12R)-(+)-12-methyl-13-tridecanolide, a constituent of Angelica root oil, Angelica archangelica L. The approach is taken as it was anticipated that CF2 groups would dictate corner locations in the macrocycle and limit the conformational space available to the lactone. Three fluorine containing lactones are prepared by organic synthesis. One (8) has CF2 groups located at the C-6 and C-9 positions, another (9) with CF2 groups at the C-5 and C-9 positions, and a third (10) with a CF2 group at C-8. Two of the fluorine containing lactones (8 and 10) were sufficiently crystalline to obtain X-ray crystal structures which revealed that the CF2 groups do adopt corner locations. All three lactones were subject to computational analysis at the B3LYP-D3/6-311+G?? level to assess the relative energies of different conformers. In all cases, the global minima and most of the lowest energy minima have squared/rectangular geometries and located the CF2 groups at the corners. The lowest energy structures for 8 and 10 closely approximated the observed X-ray structures, suggesting good convergence of theory and experiment in determining relevant low energy conformations. All three compounds retained a pleasant odour suggesting the rings retained sufficient conformational flexibility to access relevant olfactory conformations.

Catalytic asymmetric synthesis of trisubstituted aziridines

A method is described which provides for the direct asymmetric catalytic synthesis of trisubstituted aziridines from imines and diazo compounds. While unactivated imines were not reactive to alpha-diazo carbonyl compounds in which the diazo carbon was disubstituted, N-Boc imines react with both alpha-diazo esters and alpha-diazo-N-acyloxazolidinones to give trisubstituted aziridines with excellent diastereo- and enantioselectivities.

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.HPLC of Formula: C3H5NO2, you can also check out more blogs about497-25-6

Approaches to Obtaining Fluorinated alpha-Amino Acids

Fluorine does not belong to the pool of chemical elements that nature uses to build organic matter. However, chemists have exploited the unique properties of fluorine and produced countless fluoro-organic compounds without which our everyday lives would be unimaginable. The incorporation of fluorine into amino acids established a completely new class of amino acids and their properties, and those of the biopolymers constructed from them are extremely interesting. Increasing interest in this class of amino acids caused the demand for robust and stereoselective synthetic protocols that enable straightforward access to these building blocks. Herein, we present a comprehensive account of the literature in this field going back to 1995. We place special emphasis on a particular fluorination strategy. The four main sections describe fluorinated versions of alkyl, cyclic, aromatic amino acids, and also nickel-complexes to access them. We progress by one carbon unit increments. Special cases of amino acids for which there is no natural counterpart are described at the end of each section. Synthetic access to each of the amino acids is summarized in form of a table at the end of this article with the aim to make the information easily accessible to the reader.

Ciprofloxacin-induced acute psychosis in a patient with multidrug-resistant tuberculosis

Tuberculosis (TB) increasingly appears in a multidrug-resistant form (MDR-TB) in Europe, too. Treatment remains difficult due to various side effects of the multi-drug-regimens. Ciprofloxacin is widely used as one of the few TB-second-line drugs. We report on the course of a ciprofloxacin-induced acute psychosis in a patient with MDR(isoniazid, streptomycin)-TB which resolved after cessation of ciprofloxacin treatment and introduction of a novel oxazolidone. Careful treatment considerations particularly in patients with additional predisposing factors to neuropsychiatric symptoms are recommended in the potentially dangerous MDR-TB, thus creating an enormous therapeutic challenge.

Rapid synthesis of 3-amino isocoumarin derivatives from ynamides

A novel and efficient fast synthesis of 3-amino isocoumarins in good to excellent yields is reported. These interesting scaffolds can be obtained either in a single step from readily available ynamides or in a two-step sequence from the corresponding alkynyl bromide after C-N cross-coupling. This protocol, which only requires a Br¡ãnsted or Lewis acid as a promoter, offers an alternative approach toward synthesizing 3-substituted isocoumarins under smooth and fast conditions.
