Rassadin, Valentin A. published the artcileSynthesis of benzannulated sultams by intramolecular Pd-catalyzed arylation of tertiary sulfonamides, SDS of cas: 101420-79-5, the publication is Beilstein Journal of Organic Chemistry (2017), 1932-1939, database is CAplus and MEDLINE.
A new and efficient approach to five- and six-membered benzannulated sultams I [R = H, Me, 4-MeOC6H4CH2; R1 = H, Me, Cl, CO2Me, CO2Et; R2 = H, OMe, CN; n = 0, 1] by intramol. C-arylation of tertiary 1-(methoxycarbonyl)methanesulfonamides under palladium catalysis was described. In case of the α-toluenesulfonamide derivative, an unexpected formation of a 2,3-diarylindole was observed under the same conditions. The 4-methoxybenzyl group was a suitable protective group for the sultam synthesis since it was stable under the reaction conditions and could be easily removed by acidolysis with trifluoroacetic acid.
