Rhodium-catalysed hydroformylation and carbonylation of N-alkenyl-1,3-diaminopropanes
摘要:
The rhodium catalysed reactions of N-alkenyl-1,3-diaminopropanes with H-2/CO usually give mixtures of diazabicycloalkanes and aminopropyl lactams. The chemo-and regioselectivity of these reactions are influenced by the choice of ligand and by the ratio of H-2 and CO in the gas mixture and in some cases formation of a single compound can be achieved.

We report a general visible-light-mediated strategy that enables the construction of complex C(sp3)-rich N-heterospirocycles from feedstock aliphatic ketones and aldehydes with a broad selection of alkene-containing secondary amines. Key to the success of this approach was the utilization of a highly reducing Ir-photocatalyst and orchestration of the intrinsic reactivities of 1,4-cyclohexadiene and
