Synthesis of Methyl 2-Aryl-5-chlorosulfonyl-1,3-oxazole-4-carboxylates and Their Reactions with Amines and Amidines

摘要

Previously unknown methyl 2-aryl-5-chlorosulfonyl-1,3-oxazole-4-carboxylates have been synthesized. Their reactions with amines and amidines have yielded the corresponding sulfonamides and 6H, 7H-[1,3]oxazolo[5,4-d] pyrimidin-7-ones.
