Diastereoselective Three-Component 3,4-Amino Oxygenation of 1,3-Dienes Catalyzed by a Cationic Heptamethylindenyl Rhodium(III) Complex

The direct oxyamination of olefins is a compelling tool to rapidly access β-amino alcohols–a privileged motif ubiquitous in natural products, pharmaceuticals and agrochemicals. Although a variety of expedient methods are established for simple alkenes, selective amino oxygenation of 1,3-dienes is less explored. Within this context, methods for the oxyamination of 1,3-dienes that are selective for the internal position remain unprecedented. We herein report a modular three-component approach to perform an internal and highly diastereoselective amino oxygenation of 1,3-dienes catalyzed by a cationic heptamethylindenyl (Ind*) Rh(III) complex.
