Reactions of aroxy- and arylsulfanylacetic acids and their esters with N-(2,2,2-trichloro-1-hydroxyethyl)sulfonamides and -carboxamides

C-Amidoalkylation of aroxy- and arylsulfanylacetic acids and their methyl esters was effected by reaction with N-(2,2,2-trichloro-1-hydroxyethyl) sulfonamides and -carboxamides in the presence of methane-or trifluoromethanesulfonic acids as catalyst and s

C-amidoalkylation of the esters of aroxy- and arylthioacetic acids with trichloroethylidenarenesulfonamides

Esters of aroxyacetic and arylthioacetic acids react with chloral arenesulfonylimines in the presence of oleum affording in good yields the products of C-arenesulfonylamidoalkylation of the aromatic ring in 4 position.
