摘要:

以可生物降解和可重复使用的β-环糊精为超分子催化剂,在水介质中采用简易方法合成了氮取代的1,8-二氧-十氢吖啶,所得产物的收率很高,选择性也为中等到较高.该过程为双甲酮、芳香醛和芳香胺三组分通过串联Michael加成反应一步合成得到产物.本文提供了一个高效且环境友好的合成氮取代的1,8-二氧-十氢吖啶的新方法.

Abstract:

We demonstrate a superficial method for the synthesis of N-substituted 1,8-dioxo-decahydroacridines using β-cyclodextrin as a supramolecular, biodegradable, and reusable catalyst in aqueous medium. The reaction product is in excellent yield with moderate to excellent selectivity. The mechanistic transformation presumably proceeds via a one-pot, multicomponent cyclization of dimedone in the presence of aromatic aldehydes and aromatic amines/INH, undergoing a tandem Michael addition reaction. The proposed approach in this study provides a highly efficient and environmentally benign route to N-substituted 1,8-dioxo-decahydroacridines.
