摘要
以光学活性L-乳酸为原料,经还原得(2S)-1,2-丙二醇(2),再经亚硫酰环化、亲核加成及酸解反应,得到手性合成子(3S)-β-羟基丁酸,收率58.4%(以化合物2计),光学纯度大于90%。
A practical synthesis of (3S) β hydroxybutanoic acid from L lactic acid is presented. The key step of the synthesis is the nucleophilic addition to cyclic 1,2 sulfite of (S) 1,2 propanediol(2). The title acid was prepared with 58.4% overall yield(based on 2) and 90% optical purity.
