(S)-3,3-Diphenyl-1-methylpyrrolidino[1,2-c]-1,3,2-oxazaborole Usage And Synthesis
Reaction
  1. Convenient catalyst for the enantioselective borane reduction of ketones at ambient temperatures.
  2. Asymmetric synthesis of α-chiral hydroxyalkylphosphines via a catalytic, enantioselective reduction of acylphosphines.
  3. Nickel-catalyzed cross-couplings of benzylic pivalates with arylboroxines: Stereospecific formation of diarylalkanes and triarylmethanes.
  4. Enantioselective reduction of prochiral ketones with NaBH4/Me2SO4/(S)-Me-CBS.
