New and readily available chiral SPIROL-based diphosphinite ligands (SPIRAPO) have been prepared and employed for iridium-catalyzed asymmetric hydrogenations of quinolines, quinoxalines and 2H-1,4-bezoxazin-2-ones. While the structurally similar (R,R

2-Aroylmethylidene-1,2,3,4-tetrahydroquinolines with the appropriate substituents can be suitable precursors for the synthesis of alkaloids from Galipea officinalis (cuspareine, galipeine, galipinine, angustureine). However, only two, rather low-yiel

The diastereoselective addition of an allylic indium intermediate to chiral o-bromophenyl sulfinyl imine 4 proceeded with good levels of diastereoselectivity. The resulting homoallylic amine derivatives were transformed into lactams 7 and 12, which u
