the enantiomeric L-prolinol guanine derivative (36). Lastly, the 6-(dimethylamino)purine analogue, 37, was coupled to N-(benzyl-oxycarbonyl)-p-methoxy-L-phenylalanine to provide, after deprotection, the novel puromycin-like analogue 39. The analogues 26-29, 36, and 39 were all evaluated for antitumor and, except for 39, for antiviral activity. These compounds failed to appreciably inhibit the growth
描述了几种新颖的碳氮杂嘌呤核苷的合成,这些碳氮杂嘌呤核苷结合了氮代替环戊基部分的碳3。这些类似物均来自关键的立体化学定义的中间体N-(叔丁氧羰基)-O-[(4-甲氧基苯基)二苯甲基]-反-4-羟基-D-脯氨醇(19),总含量为61.1%从顺-4-羟基-D-脯氨酸开始的五步序列的收率。通过与三苯基膦和偶氮二羧酸二乙酯的Mitsunobu型偶联过程,将杂环碱6-氯嘌呤和2-氨基-6-氯嘌呤有效地引入吡咯烷环上。标准转化和去除保护基团得到顺式腺嘌呤(26),次黄嘌呤(27),2,6-二氨基嘌呤(28)和鸟嘌呤(29)D-脯氨醇衍生物。此外,反式-4-羟基-L-脯氨酸的相关序列提供了对映体L-脯氨醇鸟嘌呤衍生物(36)。最后,将6-(二甲基氨基)嘌呤类似物37与N-(苄氧基羰基)-对甲氧基-L-苯丙氨酸偶联,以在脱保护后提供新的嘌呤霉素样类似物39。类似物26-29。分别评估了36、36和39的抗
