A method for the regioselective O-acylation of 3,4-OH free d-glucosamines via stannylene acetal methodology was developed. From fully acetylated 2-N-trichloroacetyl-d-glucosamine, 4-OH free d-glucosamine derivatives bearing orthogonal protecting group patterns were prepared.
本研究开发了一种通过链烷醇缩醛法对 3,4-OH 游离 d-葡糖胺进行区域选择性 O-酰化的方法。从完全乙酰化的 2-N-三氯乙酰基-d-葡糖胺中,制备出了具有正交保护基团模式的 4-OH 游离 d-葡糖胺衍生物。
