Efficient and stereoselective synthetic routes to enantiomerically pure (2R,3S)- and (2R,3S)-2-amino-3,4-dihydroxybutyric acid have been developed using the stereoselective Strecker type reaction of carbonyl compounds derived from appropriately protected D-glyceraldehyde. The stereoselectivity of the cyanide addition was shown to be dependent on the presence of metal complexing agents, which is essential
利用适当衍生自羰基化合物的立体选择性斯特雷克型反应,已开发出对映体纯的(2 R,3 S)-和(2 R,3 S)-2-氨基-3,4-二羟基丁酸的高效和立体选择性合成路线受保护的D-甘油醛。已表明氰化物加成的立体选择性取决于金属络合剂的存在,这对于(2 R)-2,3-二-O-苄基-D-甘油醛是必不可少的。另外,已经进行了理论计算以合理化反应的立体化学过程。
