The allylation of aldehydes is a fundamental transformation in synthetic organic chemistry. Among the multitude of available reagents, especially allylsilanes have been established as preferred allyl source. As initially reported by Hosomi & Sakurai,

Cyclobutanols undergo an oxidative ring expansion into 1,2-dioxanols by using Co(acac)2 and triplet oxygen (3O2) as radical promoters. The formation of an alkoxy radical drives to the regioselective break of the strained ring with stabilization of a

An interrupted Schmidt rearrangement/Hosomi–Sakurai reaction of N-tosyl and S-substituted vinyl azides is reported. With BF3·Et2O as a Lewis acid promoter, the denitrogenative fragmentation of vinyl azides facilitates the generation of the N/S-sta

Herein we present a full account on the reductive Hosomi-Sakurai reaction along with some insight into the reaction mechanism. Stereoselectivity appears to be highest when the crucial carbocation intermediate, derived by protonation of the homoallyli

A novel reductive variant of the classical Hosomi-Sakurai reaction is reported. This transformation hinges on a redox-neutral, stereoselective internal reduction event under mild conditions. This operationally simple reaction relies on readily availa

A catalytic enantioselective Hosomi–Sakurai reaction of α-ketoesters has been developed. A copper(II) complex with a chiral bis(oxazoline) ligand bearing methanesulfonamide groups shows excellent catalytic activity to give α,α-disubstituted α-h
