A new highly stereoselective synthesis of pyrrolidine azasugar 1,4-dideoxy-1,4-imino-D-galacitol is being reported herein. The synthesis was achieved in a linear sequence and inexpensive chiral source (+)-diethyl tartarate was used as the starting material. The key step involved during the synthesis was Pd catalysed amino cyclization of alkenylamine, Bose modified Mitsunobu reaction and Sharpless asymmetric dihydroxylation.
本文报道了吡咯烷氮糖1,4-二脱氧-1,4-亚氨基-D-半乳糖醇的新的高度立体选择性合成。该合成以线性顺序实现,并且使用廉价的手性源(+)-酒石酸二乙酯作为起始材料。合成过程中涉及的关键步骤是Pd催化的烯胺氨基环化、Bose修饰的Mitsunobu反应和Sharpless不对称二羟基化。
