Intramolecular Oxidative Diamination and Aminohydroxylation of Olefins under Metal-Free Conditions
摘要:
A metal-free procedure that is simple to operate and convenient to handle was developed for the facile intramolecular oxidative diamination of olefins using an iodobenzene diacetate oxidant and a halide additive to furnish bisindolines at room temperature. The present reaction is featured by mild conditions, a broad substrate scope, and excellent functional group tolerance. The same protocol was successfully extended to the aminohydroxylation.

to internal alkenes affords the construction of vicinaldiamines. In the presence of a palladium catalyst, the reaction proceeds through two mechanistically different C-N bond formation reactions. It is initiated by aminopalladation, followed by a reductive amination of a palladated secondary carbon. The overall process proceeds with complete selectivity for both steps and thereby generates a convenient
