One-pot cycloaddition of the enyne sulfones 1–3 and 5 with propargylic alkoxides stereoselectively proceeds in DMF and exclusively gives the 2-ethoxy-3-ethynyl-4-methylene-2-perfluoroalkyl-3-(phenylsulfonyl)tetrahydrofurans 6a–e, 7a,b, 8a,b and 9a,b.
烯炔砜1–3和5与炔丙基醇盐的一锅环加成反应在DMF中立体选择性地进行,并专一性地生成2-乙氧基-3-乙炔基-4-亚甲基-2-全氟烷基-3-(苯磺酰基)四氢呋喃6a–e、7a,b、8a,b和9a,b。
