A direct acid catalyzed intermolecular electrocyclic rearrangement process for the preparation of linear and cyclic homoallylic ester and amides. A one step intermolecular electrocyclic rearrangement process includes the step of reacting a beta, gamma-unsaturated aldehyde or ketone, in which the beta, gamma-unsaturation is not part of an aromatic ring, with another aldehyde or a secondary aldimine in the presence of an acid.
一种直接酸催化的分子间电环重排过程,用于制备线性和环状同型烯基酯和酰胺。该一步分子间电环重排过程包括以下步骤:在酸的存在下,将一种β,γ-不饱和醛或酮(其中β,γ-不饱和度不是芳环的一部分)与另一种醛或次级醛亚胺反应。
