An asymmetric synthesis of cis- and trans- 5-hydroxy-(D)-pipecolic acid, starting from glycinate Schiff bases is described. The approach involves the stereoselective alkylation to generate an unsaturated side chain which on cyclisation leads to the desired trans- or cis- 5-hydroxy-(D)-pipecolic acid.
描述了从甘氨酸的席夫碱开始的不对称合成顺式和反式5-羟基-(D)-哌酸。该方法涉及立体选择性烷基化以产生不饱和侧链,该不饱和侧链在环化时产生所需的反式或顺式5-羟基-(D)-哌酸。
