Highly enantioselective reduction of 1,2-bis(p-methoxyphenylimino)-1,2-diphenylethane was conducted even with 0.5 mol% of new oxazaborolidine derived from L-threonine and a stoichiometric amount of BH3·THF to give 1,2-diphenylethylenediamine derivative in excellent enantiomeric purity. The subsequent deprotection of nitrogen atoms afforded (R,R)-1,2-diphenylethylenediamine in enantiomerically pure form.
