The DielsâAlder reaction of sulfoxide 2 with 1,3-dienes in CH2Cl2 afforded the corresponding CF3-containing mono- and polycycloadducts. In the case of the reaction of sulfoxide 2 and sulfonium salt 10 with cyclopentadiene, a mixture of four diastereomers was formed. The rotational potential energy surface (PES) of reagents 2, 10 was calculated and gave three minimum energy conformations with SO, Ph or the lone pair synperiplanar to the carbonâcarbon double bond.
在 CH2Cl2 中,亚砜 2 与 1,3-二烯发生 DielsâAlder 反应,生成了相应的含 CF3 的单加载体和多加载体。在亚砜 2 和锍盐 10 与环戊二烯的反应中,生成了四种非对映异构体的混合物。通过计算试剂 2 和 10 的旋转势能面 (PES),得出了 SO、Ph 或孤对子与碳碳双键同位的三种最小能量构象。
