摘要

Abstract A simple and efficient methodology toward the synthesis of highly molecularly diverse 2, 6-disubstituted 3, 4-dihydropyrimidin-4 (3H)-ones of type 3 has been developed. The methodology is based on a selective O-alkylation reaction with i-PrOH under Mitsunobu conditions followed by a nucleophilic heteroaromatic ipso-substitution of sulfones 20 and subsequent acidic hydrolysis of the isopropoxy group.
