Abstract
Due to the high reactivity of cyclopropanes, different methods have been developed for their stereo- and regio-controlled ring-opening reactions to achieve a variety of synthetically useful targets. The traditional methods for the ring-opening include thermolysis, use of oxidants, transition metals or radical precursors in which many of them encounter various difficulties. In the past several years, visible-light-mediated photoredox reactions received considerable attention for various organic transformations. Several methodologies have been developed in recent times for the visible-light-mediated ring-opening reactions of cyclopropanes. Considering the synthetic potential of this class of reactions, we provide a summary of various methodologies developed for the cyclopropane ring-opening reactions under visible-light photoredox catalysis.
