Urea-directed carbonylative insertion of Rh(I)-catalysts into one of the two proximal C-C bonds of aminocyclopropanes, e.g., I [R = Ph, OMe, NMe2, NMeOMe], generates rhodacyclopentanone intermediates, e.g., II. These are trapped by N-tethered alkynes to provide a (3+1+2) cycloaddition protocol that accesses N-heterobicyclic enones, e.g., III. Stoichiometric studies on a series of model rhodacyclopentanone complexes outline key structural features and provide a rationale for the efficacy of urea directing groups. A comprehensive evaluation of cycloaddition scope and a ‘second generation’ cationic Rh(I)-system, which provides enhanced yields and reaction rates for challenging substrates, are presented.
《Directed carbonylative (3+1+2) cycloadditions of amino-substituted cyclopropanes and alkynes: reaction development and increased efficiencies using a cationic rhodium system》 provides a strategy for the preparation of materials with excellent comprehensive properties, which is conducive to broaden the application field of this compound(Tris(3,5-bis(trifluoromethyl)phenyl)phosphine)SDS of cas: 175136-62-6.
