Moenomycin A (18) on reaction with the diazonium salt derived from bifunctional (protected) 15 yields the coupling product 19 which on reduction is converted into the moenomycin thiol derivative 21. Thiol 21 has been used to prepare selectively moenomycin dansyl and biotin adducts 26 and 28, respectively. This work was performed with the aim to use moenomycin as a tool for studies of the transglycosylation
Moenomycin A(18)与衍生自双功能(受保护的)15的重氮盐反应生成偶联产物19,偶联产物19还原后转化为Moenomycin硫醇衍生物21。硫醇21已分别用于选择性地制备新霉素丹磺酰基和生物素加合物26和28。进行这项工作的目的是使用莫能霉素作为研究肽聚糖生物合成中转糖基化步骤的工具。
