conjugate adducts with high diastereoselectivity. Treatment of the adducts with SnCl 4 generated benzyl carbocations which reacted intramolecularly with suitably-positioned aromatic rings to give tetralins and indanes, again with high diastereoselectivity.
使用两步序列以高度立体选择性的方式制备了重取代的 1-芳基四氢萘和 1-芳基林丹。叔丁基苄基亚砜与不饱和羰基化合物的加成得到具有高非对映选择性的共轭加合物。用 SnCl 4 处理加合物产生苄基碳正离子,它们与适当位置的芳环发生分子内反应,得到四氢萘和茚满,同样具有高非对映选择性。
