has been reported through a high-yielding reaction scheme starting from 6-chloro-2-amino purine. Crystal structures of two intermediates confirmed the formation of N9-regioisomer. This new synthetic route can potentially replace the conventional tedious method with moderate overall yield. Graphical Abstract
摘要 N2-(异丁酰基)-9-(羧甲基)
鸟嘌呤是肽核酸合成的一个重要部分,已通过从 6-
氯-
2-氨基嘌呤开始的高产反应方案进行了报道。两种中间体的晶体结构证实了 N9 区域异构体的形成。这种新的合成路线可能会以中等的总收率取代传统的繁琐方法。图形概要
