Md. Crozet et al., Synthesis of functionalized 5-nitrouracil derivatives involving electron transfer coupling reactions, HETEROCYCLE, 55(7), 2001, pp. 1271
The tetrabutylammonium salts of 1,3-dialkyl-6-methyl-5-nitrouracils reacted
with reductive alkylating agents, p-nitrobenzyl chloride and 2,2-dinitropr
opane, by electron transfer coupling reactions to yield new potentially act
ive and highly functionalized uracil derivatives.
