from (phenylthiomethyl)phenyl sulfone to a selection of aryl ω-alkenyl ketones gives adducts that via a sequence of Lewis acid catalyzed rearrangement, α-allylation, and metathesis give rise to 2-thio-4-cycloalkenones. These in turn give cycloalkadienones upon oxidation and elimination. An attempt to develop a polymer-supported variant fails because of the reversibility of sulfone anion addition.
将衍生自(苯硫基甲基)苯基砜的阴离子加到选择的芳基ω-链烯基酮上,得到加合物,该加合物通过路易斯酸催化的重排,α-烯丙基化和复分解生成2-硫基-4-环烯酮。这些继而在氧化和消除时产生环链二烯酮。由于砜阴离子加成的可逆性,开发聚合物支持的变体的尝试失败。
