Regioselective syntheses of 3-hydroxy-4-aryl-3,4,5-trihydro-2H-benzo[b][1,4]diazepin-2(1H)-ones and 3-benzylquinoxalin-2(1H)-ones from arylglycidates when exposed to 1,2-diaminobenzenes

Representatives of two pharmacologically significant classes of compounds – 3-hydroxy-4-aryl-3,4,5-trihydro-2H-benzo[b][1,4]diazepin-2(1H)-ones and 3-benzylquinoxalin-2(1H)-ones – obtained in reactions of 1,2-diaminobenzenes with methyl 3-arylglycidates in boiling acetic acid. Substituents in arylglycidates determine the direction of processes. Electron withdrawing substituents (NO2), halogen atoms (Cl, Br, F), as well as the absence of substituents, provide the formation of benzo[b][1,4]diazepin-2(1H)-one derivatives, and electron donating groups (OMe, Me) contribute to the formation of 3-benzylquinoxalin-2(1H)-ones. As a result, a new rare representatives of 3-hydroxy-4-aryl-3,4,5-trihydro-2H-benzo[b][1,4]diazepin-2(1H)-ones were obtained and a new method for producing 3-benzylquinoxalin-2(1H)-ones has been proposed.

Design and synthesis of 3-fluoro-2-oxo-3-phenylpropionic acid derivatives as potent inhibitors of 4-hydroxyphenylpyruvate dioxygenase from pig liver

Several rationally designed analogs of 3-fluoro-2-oxo-3-phenylpropionic acid were chemically synthesized, and the reactions of the hydrate form of these compounds with 4-hydroxyphenylpyruvate dioxygenase from pig liver as inhibitors were examined. Compounds 14a and 14b were found to be potent competitive inhibitors of the enzyme with K(i) values of 10 and 22μM, respectively. Copyright (C) 1999 Elsevier Science Ltd.

A convenient synthesis of aziridine-2-carboxylic esters

Optically active oxirane-2-carboxylic esters, prepared from allylic alcohols employing the Sharpless epoxidation, were treated with sodium azide.The azido alcohols obtained were subsequently converted into aziridine-2-carboxylic esters by reaction with triphenylphosphine, in good yields and with high optical purity.Various racemic oxirane-2-carboxylic esters were subjected to the same sequence of reactions.

REACTION OF 4-SUBSTITUTED BENZALDEHYDES AND ACETOPHENONES WITH CHLOROACETONITRILE

Under conditions of phase-transfer catalysis or in homogeneous solution of potassium tert-butoxide the title compounds give stereoisomeric mixtures of substituted 2,3-epoxy nitriles III and IV.Alkaline hydrolysis of epoxy nitriles IV afforded the corresponding 2-arylpropanals in low yields.On treatment with methanol and potassium carbonate, epoxy nitriles III and IV were converted into epoxy esters in good yields.
