Metal-free, radical 1,6-conjugated addition of cyclic ethers with para-quinone methides (p-QMs)Electronic supplementary information (ESI) available. See DOI: 10.1039/c9ob00127a
An efficient method for metal-free C-C bond formation between p -quinone methides ( p -QMs) and cyclic ethers via a radical pathway to afford substituted diarylmethanes and triarylmethanes or to effect the α-alkylation of the cyclic ethers has been developed. Also, the synthesis of 3,3′-disubstitute...

-QMs) and cyclic ethers
via
a radical pathway to afford substituted diarylmethanes and triarylmethanes or to effect the α-alkylation of the cyclic ethers has been developed. Also, the synthesis of 3,3′-disubstituted oxindoles with stereogenic quaternary carbon centers was successfully achieved under mild reaction conditions.
