摘要: 本文发展了一种由当归内酯和邻氨基苯甲醛衍生物出发, 经Aldol/Michael串联合环反应构建四氢呋喃并[3,2-b]喹啉-2(3H)-酮类化合物的新方法。底物于DBU催化下, 在异丙醇中0 ºC反应, 即可以较高收率得到四氢呋喃并喹啉酮类衍生物, 具有条件温和, 原子经济性高, 反应速率快等优点。

Abstract:

An efficient synthesis of tetrahydrofuro[3,2-b]quinolin-2(3H)-ones from α-angelica lactone and 2-aminobenzaldehydes via a tandem Aldol-Michael addition is described. The reactions were carried out using DBU as the base in i-PrOH at 0 °C, affording tetrahydrofuro[3,2-b]quinolin-2(3H)-ones in moderate to good yields.

Key words: Aldol/Michael tandem cyclization, Tetrahydroquinoline, Furanone
