Air-stable solid prepared by a modification of Corey's procedure, on which his literature results were based. For anhydrous reagent, see (S)-2-Methyl-CBS-oxazaborolidine, L14583.

/n

Catalyst for the CBS (Corey, Bakshi, Shibata) reduction of prochiral ketones with borane-THF, with high enantioselectivity (see (S)-(-)-ɑ,ɑ-Diphenyl­prolinol, L09217): J. Am . Chem. Soc., 109, 7925 (1987):
