presented. (R,R)-1,5-Dioxa-2,6-dioxobicyclo[3.3.0]octane, the product of hydrogenation and subsequent cyclization, was obtained in high enantiomeric excess. This compound was transformed into synthetically useful (R)-4-hydroxyethyl-2-buten-4-olide.
给出了3,4-二氧己二酸二乙酯不对称氢化的结果。(- [R ,- [R)-1,5-二氧杂-2,6- dioxobicyclo [3.3.0]辛烷,氢化和随后的环化的产物,在高对映体过量得到。将该化合物转化为可合成使用的(R)-4-羟乙基-2-丁烯-4-醇化物。
