Synthesis of protected α-amino acids: Via decarboxylation amination from malonate derivatives

A general and efficient strategy for the synthesis of protected α-amino acids is reported. The method uses malonate derivatives as the starting materials and Cs2CO3 as a base at 60 degrees, giving α-amino acid derivatives in moderate yields by releasing CO2. This methodology shows broad substrate scope (primary and secondary acids), excellent functional group tolerance and high efficiency to give the desired products under mild reaction conditions. It also allows the construction of β and γ-amino acids and other unnatural products.

Cascade reactions for constructing heterocycles containing a pyrimidino-pyrazino-pyrimidine core using 1,2,4-triazole scaffolds

The regioselective cyclocondensation of aminoethyl-1,2,4-triazoles and glyoxal provides pentacyclic heterocycles in which two 7,8-dihydro-5H-6λ2-[1,2,4]triazolo[1,5-c]pyrimidine systems are connected through CH(OH) bridges generating a central piperazine-2,5-diol ring. The structure of the new compounds was elucidated based on 1H, 13C and 15N NMR spectroscopic methods. The molecular structure of the parent compound generated from aminoethyl-1,2,4-triazole was established by single crystal X-ray diffraction.

Reaction Kinetics Direct a Rational Synthesis of an HIV-1 Inactivator of Nucleocapsid Protein 7 and Provide Mechanistic Insight into Cellular Metabolism and Antiviral Activity

Mercaptobenzamide thioester SAMT-247 is a non-toxic, mutation-resistant HIV-1 maturation inhibitor with a unique mechanism of antiviral activity. NMR spectroscopic analyses of model reactions that mimic the cellular environment answered fundamental questions about the antiviral mechanism and inspired a high-yielding (64 % overall), scalable (75 mmol), and cost-effective ($4 mmol?1) three-step synthesis that will enable additional preclinical evaluation.

Selective oxidation of amines to aldehydes or imines using laccase-mediated bio-oxidation

An efficient and practical chemo-enzymatic aerobic oxidation in water of benzylamines to obtain aldehydes or imines is described. Laccase from Trametes versicolor was chosen as biocatalyst, and TEMPO (radical 2,2,6,6-tetramethylpiperidine 1-oxyl) as mediator. A study on the pH dependence of the aqueous medium allowed us to realise a fine tuning on product selectivity. Under our optimized reaction conditions, the bio-oxidation of a series of primary, secondary and cyclic amines has been achieved.

Synthesis of GABAA receptor agonists and evaluation of their α-subunit selectivity and orientation in the GABA binding site

Drugs used to treat various disorders target GABAA receptors. To develop α subunit selective compounds, we synthesized 5-(4-piperidyl)-3-isoxazolol (4-PIOL) derivatives. The 3-isoxazolol moiety was substituted by 1,3,5-oxadiazol-2-one, 1,3,5-oxadiazol-2-thione, and substituted 1,2,4-triazol-3-ol heterocycles with modifications to the basic piperidine substituent as well as substituents without basic nitrogen. Compounds were screened by [3H]muscimol binding and in patch-clamp experiments with heterologously expressed GABAA αiβ 3γ2 receptors (i = 1-6). The effects of 5-aminomethyl-3H-[1,3,4]oxadiazol-2-one 5d were comparable to GABA for all α subunit isoforms. 5-piperidin-4-yl-3H-[1,3,4]oxadiazol-2-one 5a and 5-piperidin-4-yl-3H-[1,3,4]oxadiazol-2-thione 6a were weak agonists at α2-, α3-, and α5-containing receptors. When coapplied with GABA, they were antagonistic in α2-, α4-, and α6-containing receptors and potentiated α3-containing receptors. 6a protected GABA binding site cysteine-substitution mutants α1F64C and α1S68C from reacting with methanethiosulfonate-ethylsulfonate. 6a specifically covalently modified the α1R66C thiol, in the GABA binding site, through its oxadiazolethione sulfur. These results demonstrate the feasibility of synthesizing α subtype selective GABA mimetic drugs.
