Technical Notes:
1. The PINAP family of P,N ligands is a synthetically more accessible but a similarly performing analog of the QUINAP (15-1777, 15-1778) ligand in enantioselective hydroboration, alkyne addition, and azomethine cycloaddition reactions. (Ref. 1) 2.With copper, enantioselective addition of alkynes to aldehydes to synthesize propargylamines . 3.With copper, catalytic, enantioselective, conjugate alkyne addition in aqueous media.
