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.
逐步合成方法涉及用3-(叔氨基)-2-羟丙胺取代6-氯-1,3-二烷基尿嘧啶(5和6),随后在尿嘧啶的C5上进行酰化反应,从而合成了嘧啶二酮27-33。总产率为61-89%。已经讨论了基于NMR数据的新分子的构象方面。
