(11aR)-(+)-5,6,10,11,12,13-Hexahydro-5-phenyl-4H-diindeno[7,1-cd:17ef]phosphocin, min. 97% (R)-SITCP

Reaction

1. Phosphine-catalyzed intra-and intermolecular gamma-addition of nitrogen nucleophiles to allenoates and alkynoates.
2. Catalytic asymmetric construction of the tryptanthrin skeleton via enantioselective decarboxylative [4+2] cyclization.
3. Catalytic, enantioselective carbon-oxygen bond formation – phosphine-catalyzed synthesis of benzylic esters via oxidation of benzylic C-H bonds.
4. Use of a new spirophosphine to achieve catalytic, enantioselective [4+1] annulations of amines with allenes to generate dihydropyrroles.
