Xiao, Dengming published the artcileSynthesis of a Novel Chiral Binaphthyl Phospholane and Its Application in the Highly Enantioselective Hydrogenation of Enamides, Category: esters-buliding-blocks, the publication is Organic Letters (1999), 1(10), 1679-1681, database is CAplus and MEDLINE.
A new chiral phosphine, (R,R)-1,2-bis{(R)-4,5-dihydro-3H-dinaphtho[2,1-c:1′,2′-e]phosphepino}benzene [(R,R)-binaphane] was prepared from readily accessible enantiomerically pure (R)-binaphthalenol. This ligand possesses both binaphthyl chirality and phospholane functionality. Excellent enantioselectivities (95-99.6% ee) have been observed in hydrogenation of an isomeric mixture of (E)- and (Z)-RCH:CR1NHAc [R = H, Me, CH2Ph, CHMe2; R1 = (un)substituted Ph, 2-naphthyl] by using a Rh-binaphane catalyst. These enantioselectivities are the highest reported to date for this transformation.
