(R)-(+)-2-METHYL-CBS-OXAZABOROLIDINE 1M SOLUTION IN TOLUENE (C005B-008885)

Application

CBS Catalysts for Asymmetric Reduction and Asymmetric Synthesis

(R)-(+)-2-Methyl-CBS-oxazaborolidine solution [1M in toluene] may be used as a catalyst in the asymmetric borane reduction of perfluoroalkyl ketones.
It may also be used in the preparation of:

• (-)-diospongin B
• (1R)-2-azido-1-(2,2-dimethyl-4H-1,3-benzodioxin-6-yl)ethanol
• (S)-α-deuteriobenzyl alcohol
• (3S,4R,5S)-1-(trimethylsilyl)-4,5-epoxyhex-1-yn-3-ol

Excellent catalyst of asymmetric reductions.

The CBS (Corey-Bakshi-Shibata) oxazaborolidine catalyst has been used 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.
Used in a desymmetrizing reduction leading to (S)-4-hydroxycyclohexenone.

Physical form

Precipitate may form in storage, but does not affect product quality. Gently heat product to 80−90 °C under an inert atmosphere to redissolve solids.
