DETAILS

Description (English)

Packaging
25 mL in Sure/Seal™
5 mL in glass bottle
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.
Application
CBS Catalysts for Asymmetric Reduction and Asymmetric Synthesis
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.
