摘要

When 3-(α-thiocyanobenzyl-2(1H)-one is heated, competing processes of [a]-annelation of the imidazole or thiazole rings occurs with formation of imidazo[1,5-a]- and thiazolo[3,4-a]quinoxalin - 4(5H)-ones. ... Keywords: imidazo[1,5-a]quinoxalines, thiazolo[3,4-a]quinoxalines, quinoxalines, Kornblum reaction. ... The fact that 3-(α-thiocyanobenzyl)quinoxalin-2(1H)-one (1) [1] has endocyclic imine, carbamoyl, and exocyclic benzylthiocyanate functional ...
