Unsaturated phosphonites are excellent substrates in new (3+2)-cyclization reactions with aldehydes or thioketones. The cyclisation reactions proceed smoothly at room temperature and lead to the fast formation of the previously inaccessible phosphorus heterocycles 1,3-oxa- and 1,3-thiaphosphole-3-oxides in good to excellent yields.
在与醛或硫酮的新 (3+2)-环化反应中,不饱和亚膦酸酯是极好的底物。环化反应在室温下顺利进行,并导致以前无法获得的磷杂环 1,3-oxa- 和 1,3-thiaphosphole-3-oxides 的快速形成,收率良好。
