affording five- or seven-memberedring lactones (bicyclic, tricyclic, and pentacyclic) as the principal products, often in excellent yields. Use of 2-aminostyrenes as reactants and catalytic quantities of palladium acetate and tricyclohexylphosphine, affords five-membered ring lactams in high yield and selectivity. Bicyclic and tricyclic heterocycles containing six-membered ring lactams can be synthesized

日期:2010.9
Ionic diamine rhodium complexes catalyze the hydroaminomethylation of 2-allylanilines. The reaction involves initial hydroformylation followed by reductive amination, which provides direct access to 1,2,3,4-tetrahydroquinolines and 2,3,4,5-1H-1-benzazepines. (C) 2010 Elsevier Ltd.
