(11bS)-N,N-Bis[(R)-1-phenylethyl]-dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine, 98%, (99% ee)

Technical Notes:
1.Cyclization - Enantioselective cyclization of aromatic ketimines containing alkenyl groups tethered at the meta position of an imine directing group has been achieved using 5 mol% [RhCl(coe)2]2 and 15 mol % of this (S)-BINOL -derived phos phoramidite ligand .
