Abstract

Eleven new title compounds were synthesized for the first time by treatment of alpha-(2-chloro-4-nitrophenylsulfonyl) acetophenones with several alkylating reagents in K2CO3-TEBA-DMF system via alkylation cyclization reaction, The influences of catalysts and solvents on the yield were studied. The possible mechanism of the reaction was suggested, The reaction may provide a new and convenient method for the synthesisof 1,4-benzoxathiin-4,4-dioxide derivatives.
