Reported is the stereospecific cross‐coupling of anomeric stannanes with symmetrical diselenides, resulting in the synthesis of selenoglycosides with exclusive anomeric control. The reaction proceeds without the need for directing groups and is compatible with free hydroxy groups as demonstrated in the preparation of glycoconjugates derived from mono‐, di‐, and trisaccharides and peptides (35 examples)
报道了异头锡烷与对称二硒化物的立体特异性交叉偶联,从而合成了具有独家异头控制的硒糖苷。该反应无需定向基团即可进行,并且与游离羟基相容,如从单糖、二糖和三糖和肽衍生的糖缀合物的制备中所证明的(35 个示例)。鉴于其普遍性和广泛的底物范围,本文介绍的糖基交叉偶联方法可用于合成含硒糖模拟物和糖缀合物。
