Optically active β-hydroxysulfoximines catalyze the asymmetric borane reduction of ketones affording secondary alcohols in high yields with good enantioselectivities (up to 93% ee).

(Chemical Equation Presented) Enantiomerically enriched diarylmethanols have been prepared by catalyzed asymmetric phenyl transfer reactions onto aromatic aldehydes with use of readily available β-hydroxysulfoximines as catalysts. As the aryl source, combinations of diethylzinc with either diphenylzinc or triphenylborane have been applied affording arylphenylmethanols with up to 93% ee in good yields. Various functionalized aldehydes and heterocyclic substrates are tolerated, yielding synthetically relevant products.
