Regioselective alkylation and arylation at the 6-position of pyrimidine: Synthesis of 5-alkyl-6-arylmethyl-2,4-pyrimidinediones

Abstract

5-Alkyl-2,4,6-trichloropyrimidines reacted with various nucleophiles to afford the regioselectively 6-substituted pyrimidines as the major products in good yields, which were transformed to 5-alkyl-6-arylmethyl-2,4-pyrimidinediones of a key intermediate of MKC-442.
