A synthesis of optically active N-monomethylated amino acids (V) is described. It involves a three-step process, starting from optically active amino acids (I) which are converted into their benzyl derivatives (III), subsequently methylated (IV) and finally hydrogenolyzed. The reaction sequence proceeds without racemization.
描述了旋光性N-单甲基化氨基酸(V)的合成。它涉及一个三步过程,从光学活性氨基酸(I)开始,然后将其转化为其苄基衍生物(III),随后进行甲基化(IV),最后进行氢解。反应顺序不消旋地进行。
