The alkyl radical (R1) addition reaction to ortho-X-substituted N-(benzylidene)-2-methylpropane-2-sulfinamides (X = Br, CN, CO2Me, OH and OMe) is highly diastereoselective, regardless of the electronic properties of the X group and the size of R1. Ea

The sulfinyl group in (R)-N-tert-butanesulfinyl aldimines provides efficient control of the stereoselectivity in the intermolecular reactions with alkyl radicals. The methodology is applicable to aryl, heteroaryl, benzyl, and alkynyl imines, even tho

Reactions of α-[2-(p-tolylsulfinyl)phenyl] α-methylidene carbonyl compounds 1 and 2 with alkyl radicals generated from Et3B/O2 and RI give, after protonation, β-alkyl derivatives with a high degree of control of the configuration at the α carbon.

Methylation of chiral acyclic α-methyl-β-ketosulfoxides with Me3Al and Me2AlCl is reported. Induced configuration at hydroxylic carbon is mainly controlled by the configuration of the sulfinyl group, with de's higher than 90% in most of the cases r
