Ruthenium-catalyzed [2+2] cycloadditions of bicyclic alkenes with alkynyl sulfides and alkynyl sulfones were investigated. The sulfide and sulfone moieties were found to be compatible with the Ru-catalyzed cycloadditions, giving the corresponding cyclobutene cycloadducts in good yields. The sulfonyl-containing cycloadducts can be transformed into a variety of products that are difficult to obtain via direct cycloaddition.
研究了钌催化的双环烯烃与炔基硫化物和炔基砜的[2+2]环加成反应。发现硫化物和砜基部分与钌催化的环加成反应兼容，能以良好的产率得到相应的环丁烯环加成产物。含砜基的环加成产物可转化为多种难以通过直接环加成获得的产物。
