A concise synthesis of d-desosamine has been accomplished in five steps and in 15% overall yield from methyl alpha-d-glucopyranoside. Desosamine was then transformed into two known 2-thiopyrimidinyl donors (Woodward and Tatsuta donors), each in two steps. Finally, analogues of methyl desosaminide at the C-3 position were prepared (3-pyrrolidino, 3-piperidino, 3-morpholino) from a common 2,3-anhydrosugar
d-去糖胺的简洁合成已通过五个步骤完成,并且甲基α-d-吡喃葡萄糖苷的总收率为15%。然后将去糖胺转化为两个已知的2-硫代嘧啶基供体(Woodward和Tatsuta供体),每个过程分两步进行。最后,从普通的2,3-脱水糖中间体制备了C-3位的甲基去沙酰胺的类似物(3-吡咯烷酮,3-哌啶子基,3-吗啉代)。
