A series of N-1-alkylated 6-benzyluracil-5-carboxylic esters 4a-h were synthesized by reacting imines of 3-oxo-4-phenyl-butyrates with N-(chlorocarbonyl) isocyanate. An N-1-(4-methoxy-benzyl) group could be removed in a dealkylation reaction to give the ethyl and allyl esters 5a and 5b, respectively. They were N-1-alkylated with chloromethyl ethyl ether or dialloxymethane. Unfortunately no biological
通过将 3-氧代-4-苯基丁酸酯的亚胺与 N-(氯羰基) 异氰酸酯反应合成一系列 N-1-烷基化 6-苄基尿嘧啶-5-羧酸酯 4a-h。N-1-(4-甲氧基-苄基)基团可以在脱烷基化反应中除去,分别得到乙基酯和烯丙基酯5a和5b。它们用氯甲基乙基醚或二烷氧基甲烷进行N-1-烷基化。不幸的是,没有观察到任何合成化合物对 HIV-1 和 HSV 的生物活性。
