The synthesis of nucleoside 6, via a regio- and stereoselective N-glycosylation of the undecose glycoside 4, is described. Nucleoside 6 is the first synthetic analogue of the herbicidin class of antibiotics to be reported and this model study also offers an insight into the scope and limitations associated with more general synthetic strategies based on a ‘late stage’ N-glycosylation.
本文介绍了通过对
十一烷糖苷 4 进行区域和立体选择性 N-糖基化合成核苷 6 的过程。核苷 6 是首次报道的草本苷类抗生素的合成类似物,这项模型研究还让人们深入了解了基于 "后期 "N-糖基化的一般合成策略的范围和局限性。
