Ethers of chiral hydroxy carboxylic esters and their derivatives are having wide synthetic applications both as chiral building blocks for the synthesis of biologically important molecules' as well as in the synthesis of novel chiral phase-transfer catalysts such as 3.2 Our interest in the preparation of diverse non-flexible chiral phase-transfer catalysts as shown in Scheme I, led us to synthesize
手性羟基羧酸酯的醚及其衍生物具有广泛的合成应用,既可作为合成重要生物分子的手性构件,也可用于合成新型手性相转移催化剂,例如 3.2 我们对制备各种如方案 I 所示的非柔性手性相转移催化剂使我们合成了各种酒石酸醚。为了制备la的苄基醚,
