Facile selective synthesis of new furo[3,4-d]-1,3-thiazoles
摘要:
In presence of triethylamine, the reaction of substituted 2-aroyl-hydrazinecarbothioamides with 1,4-Diphenyl-but-2-yne-1,4-dione afforded novel furo[3,4-d]-1,3-thiazoles in good yield. The reaction mechanism suggests that the second molecule of 1,4-Diphenyl-but-2-yne-1,4-dione behaved as an oxidizing agent.[GRAPHICS].
