Visible-light-mediated metal-free decarboxylative acylations of isocyanides with α-oxocarboxylic acids and water leading to α-ketoamides†
Abstract
An efficient visible-light-promoted approach for preparing α-ketoamides from α-oxocarboxylic acids, isocyanides and water is disclosed. The present transformation could be achieved under mild and metal-free conditions through a sequence of decarboxylation, radical addition and hydration processes, which provides a novel and facile route to construct α-ketoamides from simple and readily available chemical feedstocks.
