Significance

This work outlines a multicomponent reaction between a diazoacetate, water, and an α,β-unsaturated ketone. Diazoacetate reacts with water to generate oxonium ylides, which have been reacted with aldehydes and imines previously, but this is reportedly the first example of a reaction with a Michael acceptor. The transformation yields γ-hydroxy ketones with contiguous quaternary and trisubstituted stereocenters.
