(S)-3,3-Diphenyl-1-methylpyrrolidino[1,2-c]-1,3,2-oxazaborole Chemical Properties,Usage,Production
Reaction
- Convenient catalyst for the enantioselective borane reduction of ketones at ambient temperatures.
- Asymmetric synthesis of α-chiral hydroxyalkylphosphines via a catalytic, enantioselective reduction of acylphosphines.
- Nickel-catalyzed cross-couplings of benzylic pivalates with arylboroxines: Stereospecific formation of diarylalkanes and triarylmethanes.
- Enantioselective reduction of prochiral ketones with NaBH4/Me2SO4/(S)-Me-CBS.
Chemical Properties
Colorless to yellow liquid
Uses
(S)-2-Methyl-CBS-oxazaborolidine is used as an oxazaborolidine catalyst. It is also employed in the asymmetric reduction of prochiral ketones. Other applications include the enantioselective synthesis of α-hydroxy acids, α-amino acids, C2-symmetrical ferrocenyl diols and propargyl alcohols. It is an anhydrous catalyst for 'CBS' reduction reaction.
