yl)oxyl (TEMPO) in the presence of rutheniumphotoredoxcatalysis is reported. The key transformation entails a highly efficient photoredox catalytic cycle using Hantzsch ester as a reductant. The ensuing alkoxyamine can be readily converted to the corresponding alcohol in one pot, representing an alternative approach to access aliphatic alcohols under photoredox conditions.
manuscript reports a visible light-mediated organosul-fide catalysis that enables the decarboxylative coupling between simple aliphaticalcohol and tertiary or secondary alkyl carboxylic acid-derived redox active esters to produce a C(sp3)-O-C(sp3) fragment. Results of the coupling using other heteroatom nucleophiles such as water, amides and thiols are also described.
