Pre-treatment with &agr;,&bgr; unsaturated aryl sulfones protects normal cells from the cytotoxic side effects of two classes of anticancer chemotherapeutics. Administration of a cytoprotective sulfone compound to a patient prior to anticancer chemotherapy with a mitotic phase cell cycle inhibitor or topoisomerase inhibitor reduces or eliminates the cytotoxic side effects of the anticancer agent on normal cells. The cytoprotective effect of the &agr;,&bgr; unsaturated aryl sulfone allows the clinician to safely increasing the dosage of the anticancer chemotherapeutic.

gives highly regio- and stereoselectively (E)-α-stannylvinyl sulfones 2 in high yields. (E)-α-Stannylvinyl sulfones 2 are new difunctional group reagents which undergo Stillecoupling reactions with acyl chlorides 3 to afford stereoselectively (Z)-α-arylsulfonyl-α,β-unsaturatedketones 4 in good yields. A one-pot stereoselectivesynthesis of (Z)-α-arylsulfonyl-α,β-unsaturatedketones 4 has also been achieved

Pre-treatment with &agr;,&bgr; unsaturated aryl sulfones protects normal cells from the toxic side effects of ionizing radiation. Administration of a radioprotective &agr;,&bgr; unsaturated aryl sulfone compound to a patient prior to anticancer radiotherapy reduces the cytotoxic side effects of the radiation on normal cells. The radioprotective effect of the &agr;,&bgr; unsaturated aryl sulfone allows the clinician to safely increase the dosage of anticancer radiation. In some instances, amelioration of toxicity following inadvertent radiation exposure may be mitigated with administration of &agr;,&bgr; unsaturated arylsulfone.
