The first kinetic resolution of β-hydroxy epoxides has been studied through chiral aluminium reagents, which gave the recovered starting material with 60% ee. Various conditions were explored for the kinetic resolution of β-hydroxy epoxide by chiral aluminium reagents. A possible mechanism was proposed for the reaction by aluminium reagent.

Key words: kinetic resolution, β-hydroxy epoxide, chiral BINOL, triethylaluminium
