Regioselective Acid -Catalyzed Cyclization Reaction: Unique Synthesis of Condensed Thiazoles and Selenazole
摘要:
The facile and regioselective synthesis of condensed thiazoles 7-11 and selenazole 12 has been performed by the catalytic action of H2SO4 on corresponding propynylthio 1-5 and propynylseleno 6 derivatives respectively.

Abstract The reaction of 2-(prop-2-ynylsulfanyl)pyrimidone 1 with various iodobenzenes in the presence of a palladium catalyst leads to regioselective cyclization to 3-benzylthiazolo [3,2-a] pyrimidones 3. The reaction of 4-(prop-2-ynylsulfanyl) pyrimidone 5 with various iodobenzenes in the same condition give the corresponding 3-benzylthiazolo[3,2-c]pyrimidones 6.
