Chemo- and regioselective functionalization of uracil derivatives. Applications to the synthesis of oxypurinol and emivirine

A novel route for the synthesis of 4,5-difunctionalized uracils using a chemo- and regioselective bromine/magnesium exchange reaction on 5-bromo-4-halogeno-2,6-dimethoxypyrimidines has been developed. Applications to the synthesis of pharmaceuticals such as oxypurinol and emivirine are reported.

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

5-Alkyl-2,4,6-trichloropyrimidines reacted with various nucleophiles to afford the regioselectivity 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
