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.
