Reduction of epoxides 1, 2, 3 with LAH and LAH/AlCl3 has been studied. The products of reduction with LAH were controlled by steric and stereoelectronic effects. The reduction with LAH/AlCl3 seemed to involve an intermediate in which one aluminum ion was shared by both oxygen atoms from the epoxide and the tetrahydrofuran ring.
