Convenient and efficient reduction of 1,1′-binaphthyls to H8-1,1′-binaphthyl derivatives with Pd and Ru catalysts on solid support

Hydrogenation of chiral 2,2'-functionalized 1,1'-binaphthyls with Pd and Ru solid-supported metal catalysts was found to be a clean and convenient pathway to 5,5',6,6',7,7',8,8'-octahydro-1,1'-dinaphthyl derivatives. In most cases no racemization was observed in the course of the reaction.
