Rhodium(I) Catalyzed Hydroacylation Reactions of Alkenyl Compounds

Abstract

AbstractTransition‐metal‐catalyzed hydroacylation of unsaturated substrates with aldehydes involving the formyl C(sp2)−H bond activation provides an expedient and efficient access to the carbonyl compounds such as ketones and esters, which are a class of important scaffolds in natural products and in drug development. Recently, extensive attention has been paid to the hydroacylation reactions of the components containing an alkenyl moiety that can trigger a regioselective transformation in the presence of a transition metal catalyst. In this review, we summarize the constructive endeavors in rhodium(I)‐catalyzed (formal) hydroacylation reactions from 2018, and the plausible pathway is also dissected to offer some insights into the reaction mechanism.
