(+)-serine or (-)-serine, as appropriate, convenient, high-yield, enantioselective synthesis of all eight stereoisomeric 2-hydroxymethyl-3,4-dihydroxypyrrolidines (the enantiomeric pairs of iminoribitol, -arabinitol, -xylitol, and -lyxitol) can be effected. The absolute configuration of the starting amino acid defines the set of azasugars produced.
从(+)-丝氨酸或(-)-丝氨酸开始,视情况,方便,高产,对映选择性合成所有八个立体异构体2-羟甲基-3,4-二羟基吡咯烷酮(亚氨基核糖醇,-阿拉伯糖醇,-木糖醇的对映体对) ,和-lyxitol)。起始氨基酸的绝对构型定义了所产生的氮杂糖的集合。
