An improved diphosphine-iridium (I) catalyst system for the asymmetric hydrogenation of cyclic imines: Phthalimide as an efficient co-catalyst
The asymmetric hydrogenation of cyclic ketimines, 1-alkyl-3,4-dihydroisoquinolines 5a,b was carried out with diphosphine-iridium(I) complex catalysts in the presence of various imides or amides as a co-catalyst. Remarkable effects of five-membered imides on the enantioselectivity and the catalytic activity were observed. The enantioselectivity with a BCPM 1-iridium(I) complex was much improved up to 93% ee by addition of phthalimide.
