AbstractA catalyst-free multicomponent reaction capable of affording a wide range of eighteen novel chromeno[4,3-b]quinolone derivatives (6a–6r) via one-pot two-step domino protocol, in ethylene glycol is reported. Catalyst-free conditions along with green solvent system make the process eco-friendly as well as economical. High yields of the products were obtained in short reaction times by forming
摘要报道了一种无催化剂的多组分反应,该反应能够通过一锅两步多米诺协议在
乙二醇中提供十八种新颖的chromeno [4,3- b ] quinolone衍
生物(6a-6r)。不含催化剂的条件以及绿色溶剂系统使该工艺既环保又经济。通过在一次操作中形成三个新的键和一个立体中心,可在较短的反应时间内获得高产率的产物。本方案的突出特点是反应时间短,环保溶剂,高收率和后处理程序容易。 图形概要:概述报告了一种无催化剂的多组分反应,该反应可通过一锅两步多米诺协议在
乙二醇中提供多种新型的
铬诺[4,3- b ]
喹诺酮衍
