Reactions of methyl chloro(phenyl)pyruvate with 1,3-bis(phenylthioureido)benzene easily afforded 1,3-bis(4-hydroxy-4-methoxycarbonyl-3,5-diphenylthiazolidin-2-ylideneamino)benzene. Reactions of the latter with 1,2-phenylenediamines gave various derivatives of thiazolo[3,4-a]quinoxalines, including their bisanalogs.
氯(苯基)丙酮酸甲酯与 1,3-双(苯基硫脲基)苯的反应很容易得到 1,3-双(4-羟基-4-甲氧羰基-3,5-二苯基噻唑烷-2-亚基氨基)苯。后者与 1,2-苯二胺反应生成噻唑并 [3,4-a] 喹喔啉的各种衍生物,包括它们的双类似物。
