| Technical Note: 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 decarboxylativo [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, enantios elective [4+ 1] annulations of amines with allenes to generatedihydropyrroles.
