Both enantiomers of cis-4-hydroxypipecolic acid have been prepared by asymmetric synthesis using (S)- or (R)-glycidol as the chiral source, and involving a stereoselective hydrogenation of a six-membered cyclic imine. The latter is obtained by reduction and cyclization of a cyano β-hydroxy ketone.
顺式-4-羟基哌酸的两种对映体都是通过不对称合成制备的,使用(S)-或(R)-缩水甘油作为手性来源,并且涉及六元环状亚胺的立体选择性氢化。后者通过氰基β-羟基酮的还原和环化获得。
