Abstract: A P-chiral phosphinite borane complex, C₁₇H₂₀BF₃NOP, derived from (2R,4S,5R)-2-chloro-3,4-dimethyl-5-phenyl-1,3,2-oxazaphospholidine and [4-(trifluoromethyl)phenyl]magnesium bromide is reported. The absolute configuration (R at P) is deduced from the known chirality of (1R,2S)-ephedrine and confirmed by the refinement.
