The reduction of dibenzylketoxime (Ia) with LAH in boiling THF gave cis-2-phenyl-3-benzyl- aziridine (IIa) in excellent yield, together with a small amount of the expected primary amine, 2-amino-1, 3-diphenylpropane (III). The LAD reduction of Ia was carried out and the position of deuterium introduced was based on the NMR data. The O-substituted derivatives of Ia, such as O-Me, O-acetyl and O-tosyl derivatives (Ib, Ic and ID), were also reduced with LAH ...
