Aplicaciones

(S)-2-Methyl-CBS-oxazaborolidine is used as an oxazaborolidine catalyst. It is also employed 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 an anhydrous catalyst for 'CBS' reduction reaction.

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. Incompatible with oxidizing agents.
