A visible-light-induced radical relay strategy was reported for the synthesis of heterocycles containing a monofluoromethylsufonyl moiety. The protocol showed high yields, mild reaction conditions, broad functional group compatibility.
A visible-light-induced radical relay strategy to access heterocycles bearing a monofluoromethylsufonyl moiety is reported, with PhI(OCOCH2F)(2) as the CH2F radical precursor and DABSO as the SO2 source. A range of oxindoles, containing a CH2FSO2CH2- group at the C3 position, were synthesized from N-arylacrylamides in up to 97% yields. The protocol features catalyst-free photochemical tandem, mild reaction conditions, broad functional group compatibility, and good to excellent yields.
