Glycidamides 6R and 6S were elaborated to (R,R)- and (S,S)-dysibetaines (1R and 1S) by intramolecular alkylation and functional group modification in 23% overall yield. The absolute stereochemistry of natural dysibetaine was established as S,S by comparison of the optical rotation of the natural product with that of the synthetic materials.
通过分子内烷基化和官能团修饰将糖苷6R和6S精制为(R,R)-和(S,S)-dysibetaines(1R和1S),总产率为23%。通过将天然产物的旋光度与合成材料的旋光度进行比较,将天然dysibetaine的绝对立体化学确定为S,S。
