摘要

Abstract The condensation of methyl phenylchloropyruvate with 1-phenyl-3-(2-pyridyl) thiourea and its 3-and 4-picolyl homologs affords the corresponding 4-hydroxythiazolidines, which react with o-phenylenediamine to give one of two possible thiazolo [3, 4-a] quinoxalines containing the pyridyl-or picolylimine substituents at position 1. 3a-Hydroxy-3- phenylimino-1-(2-pyridyl) thiazolo [3, 4-a] quinoxalin-4-(3 H, 5 H)-one, which is a covalent ...
