We have developed a novel and efficient three-component one-pot, catalytic approach for the synthesis of 2,3,4,5-tetrahydro-1H-2-benzazepines, using a rhodium catalyst that does not require phosphine. The isolated yields are excellent and the protocol tolerates anilines of diverse basicity.

Transition-metal-catalyzed hydroformylation has become an essential tool for the synthesis of aldehydes. In this paper, we highlight several examples of synthetically useful applications of homogeneous and heterogeneous rhodium-catalyzed hydroformylation, as well as several examples of tandem processes involving hydroformylation as a reaction step developed in our laboratory.
