unique tetrahydro[1,4]diazepino-[1,2,3-g,h]purine (THDAP) structure and interesting biological properties. Three synthetic approaches were employed for the preparation of the THDAP system. Several N-9, of the purine, protecting groups were investigated. 15N-Chemical shifts measured from 15NH HMBC experiments for several compounds, that demonstrate the influence of various structural features on the 15N-resonances
阿斯马林是海洋生物碱,具有独特的四氢[1,4]二氮杂卓-[1,2,3- g,h ]嘌呤(THDAP)结构和有趣的生物学特性。THDAP系统的制备采用了三种综合方法。研究了嘌呤中的几个N-9保护基。从15种NH HMBC实验中对几种化合物测得的15 N化学位移已得到报道,证明了各种结构特征对15 N共振的影响。
