Description

(R)-2-Methyl-CBS-oxazaborolidine is 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. It is also used in a desymmetrizing reduction leading to (S)-4-hydroxycyclohexenone. It is useful in the production of stereospecific motifs such as α-hydroxy acids, α-amino acids, symmetrical ferrocenyl diols and propargyl alcohols.
