Aryl azides as forgotten electrophiles in the Van Leusen reaction: a multicomponent transformation affording 4-tosyl-1-arylimidazoles
2019
Considering aryl azides as electrophilic partners for the TosMIC mediated Van Leusen reaction, a novel multicomponent synthesis of 4-tosyl-1-arylimidazoles is reported. In this transformation, two molecules of TosMIC participate in the reaction mechanism in two different ways, with the second molecule undergoing a novel type of fragmentation resulting in the incorporation of a C-H into the final product.
