Efficient enantioselective synthesis of 3-aminochroman derivatives through ruthenium-Synphos catalyzed asymmetric hydrogenation

Org Lett. 2011 Aug 5;13(15):3782-5. doi: 10.1021/ol201786q. Epub 2011 Jul 14.

Abstract

A highly enantioselective asymmetric hydrogenation of various trisubstituted enamides derived from chroman-3-ones promoted by cationic Ru-Synphos catalysts is reported. This atom-economical and clean method provides an efficient route to optically active 3-aminochroman derivatives, which are important pharmacophores found in numerous drug candidates, in high chemical yields and enantiomeric excesses up to 96%.
