Aplicaciones

(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.

Notas

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. Store under inert gas. It is sensitive to moisture and air. Incompatible with oxidizing agents.
