nates in tandem Michael addition/Horner olefination reaction leads to a wide range of carbocyclic and heterocyclic vinyl sulfoxides. In second part of this account a new strategy for the synthesis of functionalized cyclopentenones is briefly described. The synthesis and reactivity of 3-phosphorylmethyl-cyclopentenones is discussed as a platform for developing the synthesis of racemic rosaprostol, enantiomeric
本文概述了我们将霍纳烯化反应应用于合成不饱和硫化合物的工作结果。介绍了通过霍纳反应与 α-亚磺酰基甲基膦酸酯作为烯化试剂的外消旋和光学活性 α,β-不饱和亚砜的一般合成。我们展示了膦酸酯部分的结构如何控制上述反应中的 E 和 Z 立体选择性。在串联迈克尔加成/霍纳烯化反应中使用外消旋和光学活性 α-亚磺酰基乙烯基膦酸酯可产生多种碳环和杂环乙烯基亚砜。本报告的第二部分简要描述了合成功能化环戊烯酮的新策略。
