Gallium(III) Triflate Catalyzed Direct Reductive Amination of Aldehydes
摘要:
Direct hydroamination of aldehydes and ketones provides one-step entry into desired alpha-aminoalkane derivatives which are important synthons for many biologically active molecules. The reductive amination of aldehydes in the presence of silanes has been effectively promoted by Ga(OTf)(3) as a catalyst. Mild conditions, easy work-up and high purity of products with excellent yields are the major advantages of this method.
