(R)-2-Methyl-CBS-oxazaborolidine, 1M soln. in toluene

Description

CAS: 112022-83-0 | C18H20BNO | 277.17 g/mol

(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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
