Abstract: Synthetically useful radical thiol-ene reactions can be initiated by visible-light irradiation in the presence of an organic photocatalyst, 9-mesityl-10-methylacridinum tetrafluoroborate. The key thiyl radical intermediates are generated upon quenching of the photoexcited catalyst with a… read more here.

DOI: 10.1021/acsomega.7b01124
Abstract: Nitrosocarbonyl intermediates, generated at room temperature by oxidation of nitrile oxides, undergo clean ene reactions with trisubstituted cycloalkenes. Nitrosocarbonyl benzene follows a Markovnikov orientation and abstracts preferentially the twix hydrogens over the lone ones. With… read more here.

DOI: 10.1039/c8qo00233a
Abstract: A tandem approach for the stereoselective allylic reduction has been developed based on a strategy combining the palladium-catalyzed S-allylation and the sulfinyl retro-ene reactions. In a one-pot process employing various allylic carbonates, sodium t-butyldimethylsilyloxymethanesulfinate (TBSOMS-Na),… read more here.
