bearing an α-aminosulfonic acid moiety in the penultimate position have been synthesized using a Curtiusrearrangement step. The sulfonopeptides were prepared and examined in aprotic solvents, but they proved to be exceedingly labile in protic solvents; for example, α-acylaminosulfonodipeptide 31 proved to be too unstable to isolate in pure form and its methyl ester, 34, decomposed with a half-life of ca

A new and efficient approach to five- and six-membered benzannelated sultams by intramolecular C-arylation of tertiary 1-(methoxycarbonyl)methanesulfonamides under palladium catalysis is described. In case of the α-toluenesulfonamide derivative, an unexpected formation of a 2,3-diarylindole was observed under the same conditions.
