Stannane-mediated radical addition to methylideneimidazolidinones occurs with good to excellent diastereo-selectivity. The stereochemical outcome of addition is highly dependent on the nature of the N1 substituent on the imidazolidinone ring.

Substantial Progress

: This review highlights the multifaceted synthetic applications of ynones in radical reactions. Substantial progress has been made over the last decade (2010-2020) in the utilization of ynones. Herein, the chemistry of ynones is divided into three sections based on the classes of critical mechanistic insights: (1) radical addition and intramolecular cyclization; (2) radical addition and intermolecular annulation; (3) radical addition and coupling. We hope that this review will promote future research in this area.

The direct α-Csp3-H functionalization of simple ethers has emerged as one of the vital strategies among radical reactions. This review discusses their applications according to the starting materials: (1) reactions with alkenes or alkynes. (2) reactions with other unsaturated compounds. (3) reactions with nucleophilic partners. Mechanisms like radical addition, elimination, oxidation, metal-catalyzed coupling, C-H activation, cyclization and rearrangement will be discussed herein.
