Copper(I)-Catalyzed Ligand-Promoted Multicomponent Reactions of Isocyanides, Selenium, Amines, and Iodoarenes: Access to Highly Functionalized Carbamimidoselenoates.

A new and facile approach toward highly functionalized carbamimidoseleknoates was developed through the copper(I)-catalyzed ligand-promoted four-component reaction of isocyanides, selenium, amines, and aryl iodides. The reaction constructed a range of organoselenium compounds containing an isoselenourea skeleton with potential bioactivity directly from selenium powder. The simplicity of method and broad diversity of substrates also highlight this work.
