Synthesis of 4-hetaryl-substituted 5-amino- and 5-sulfanyl-1,3-oxazole derivatives
摘要:
Previously unknown 5-amino- and 5-sulfanyl-1,3-oxazole derivatives containing a 1,3,4-oxadiazole, 1,3,4-thiadiazole, or 1,2,4-triazole fragment at C-4 were synthesized from accessible 1,3-oxazole-4-carboxylic acid hydrazides.
