The synthesis and the evaluation of cytotoxicity and anti-HIV-1 activity of new aryl pyrrolyl (8) and aryl indolyl (9) sulfones are reported. Preparation of above sulfones was achieved by reacting arylsulfonyl chlorides with substituted pyrroles and indoles or by condensing sulfonamides with 2,5-dimethoxytetrahydrofuran in glacial acetic acid according to the Clauson-Kaas method. Chemical requisites

(1) a silicon oxide and/or an aluminum oxide,
(2) a magnesium halide, and
(3) an organometallic compound.
