In a lengthy study searching for new biologically-active compounds in the N-benzyluracil series [i, 6, 7], we undertook the synthesis of 6-substituted N1-(3-R-4-methoxybenzyl)-N 3- methyluracils (la-c, lla-e, and Ilia-d). The choice of these compounds was directed by the fact that some of our earlier-synthesized N-benzyluracils showed significant antitumor activity [i, 6] and N-sulfonylphenyluracil possessed antibacterial activity [5]. Further, information is ...
