title: Synthesis of 5-acyl-6-[2-hydroxy-3-(amino)propylamino]-1,3-dialkyl-1H-pyrimidine-2,4-diones.
abstract: A stepwise synthetic approach involving substitution of 6-chloro-1,3-dialkyluracils (5 and 6) with 3-(tert-amino)-2-hydroxypropylamines and subsequent acylation at C5 of uracil has been used to synthesize pyrimidinediones 27-33 in 61-89% overall yield. The conformational aspects of the new molecules based upon NMR data have been discussed.
