[bmIm]OH-catalyzed amidation of azides and aldehydes: an efficient route to amides†
Abstract
A [bmIm]OH-catalyzed amidation of azides and aldehydes is reported. This reaction is easily handled and proceeds under mild conditions. The overall transformation involves azide–enolate cycloaddition, which subsequently undergoes rearrangement to give amides. Importantly, the employment of ionic liquid makes this transformation green and practical.
