Regioselective reductions of 2, 3-epoxy-1-alkanol and its derivatives are carried out by use of lithium borohydride supported on calcium ion-exchanged Y-type zeolite.2, 3-Epoxy-substituted ether is found to be reduced at the C-3 position with the above heterogeneous reducing reagent more regioselectively than 2, 3-epoxy-1-alkanol. High regioselection is attributable to the interaction between the organic substrate and the calcium ion in the zeolite since the reducing reagent supported on sodium ion-exchanged zeolite shows low selectivity.
