Epoxides containing hydroxy groups are rearranged enantioselectively using a chiral base to give allyl alcohols in high enantiomeric excess, e.g. ##STR1## If R.sup.3 .noteq.H, the reaction also has the effect of generating a chiral tetrasubstituted carbon atom.
含有羟基的
环氧化物通过使用手性碱进行对映选择性重排,可以高对映选择性地生成
烯丙醇,例如##STR1## 如果R.sup.3 ≠ H,该反应还会产生手性四取代碳原子。
