Unactivated alkylsulfinic acids as an alkyl radical source for the synthesis of 3,3-dialkylindolin-2-ones via an electron donor-acceptor complex

Using unactivated alkylsulfinic acids as an alkyl radical source, a novel and highly practical visible-light-assisted synthetic methodology for the alkylation/annulations of a series of N-arylacrylamides into corresponding 3,3-dialkylindolin-2-ones has been...
