摘要

摘要研究了Lewis酸催化施-受体斯坦豪斯加合物(DASAs)的4π电环化反应。利用Dy(OTf)3的催化量，实现了无环dasa向相应的环化异构体的高效转化。值得注意的是，这种转变表现出了非凡的产量，特别是在第一代dasa的情况下。此外，Lewis酸催化使“供体”和“受体”组分一锅合成环戊酮产物成为可能。

Lewis Acid Catalyzed 4π-Electrocyclization of Donor-Acceptor Stenhouse Adducts

Abstract Lewis acid catalyzed 4π-electrocyclization of Donor–Acceptor Stenhouse Adducts (DASAs) has been developed. By employing catalytic quantities of Dy(OTf)3, a highly efficient transformation of acyclic DASAs into the corresponding cyclized isomers was achieved. Notably, this transformation exhibited exceptional yields, particularly in the case of first generation DASAs. In addition, Lewis acid catalysis enabled one-pot synthesis of the cyclopentenone product from the ‘donor’ and ‘acceptor’ components.
