Abstract
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.
