Phosphoramidite-Rhodium Complexes as Catalysts for the Asymmetric [2+2+2] Cycloaddition of Alkenyl Isocyanates and Alkynes
{{output}}
The discovery and development of the asymmetric rhodium-catalyzed [2+2+2] cycloaddition of alkenyl isocyanates and exogenous alkynes to form indolizinone and quinolizinone scaffolds is described. This methodology has been expanded to include substituted alkene... ...
