The model studies of uracil group introduction for liposidomycin degradation product was described. A stereocontrolled synthesis of the liposidomycin diazepanone ring system having a phenyl substituent has been achieved. In the presence of an amino group on the diazepanone ring, the introduction of a uracil group did failed. In the model study with the Ns and formyl protecting group, the N-glycosylation
介绍了脂霉素降解产物尿嘧啶基团引入的模型研究。已经实现了具有苯基取代基的脂西多霉素二氮杂环酮环系统的立体控制合成。在二氮杂环酮环上存在氨基的情况下,尿嘧啶基团的引入确实失败了。在Ns和甲酰基保护基团的模型研究中,N-糖基化反应顺利进行,以良好的收率得到了尿嘧啶化合物。
