Abstract: Alkyl and aryl halides have been studied extensively as radical precursors; however, mild and less toxic conditions for the activation of alkyl bromides toward alkyl radicals are still desirable. Reported here is a reductive radical… read more here.

DOI: 10.1021/acs.orglett.7b00187
Abstract: The most advanced approach, so far, to the asperparalines is developed. Consecutive oxidative and reductive radical cyclizations serve as the key steps to stereoselectively access the complex fully elaborated skeleton containing the cyclopentane and spiro-succinimide… read more here.

Abstract: The generation and fate of 2I-VII,3I-VII,6II-VII-icosa- O-methyl-β-cyclomaltoheptaos-6I- O-yl radical under reductive conditions is described. Two radical cascade reactions are involved: the main one is triggered by a 1,8-HAT of the hydrogen at 5VIIC. The radical… read more here.

DOI: 10.1021/jacs.0c03926
Abstract: A photocatalytic system for the dearomative hydroarylation of benzene derivatives has been developed. Using a combination of an organic photoredox catalyst and an amine reductant, this process operates through a reductive radical-polar crossover mechanism where… read more here.
