Abstract

Synthesis of 1-Amino-5,6-diaryl-3-cyano-1H-pyridin-2-ones and 6,7-Diaryl--4-cyano-3-hydroxy-1H-[1,2]diazepines from Isoflavones. -The title compounds (III) and (IV) are obtained by KOH-mediated one-step cyclocondensation of substituted flavones (I) with cyanoacetohydrazide (II). -(ZHU, M.-L.; ZHANG*, Z.-T.; XUE, D.; HUA, H.-L.; LIANG, Y.; WNUK, S.
