research, synthesis of pyrrolo isoquinoline derivatives in excellent yields was performed using the multicomponent reaction of isoquinoline, alkyl bromides, 2‐hydroxyacetophenone, or its derivatives, dimethyl carbonate as a green reagent and KF/clinoptinolite nanoparticles as a catalyst in the aqueous media at 80°C. The Punica granatum peel water extract was used as the green media for the synthesis of
在这项研究中,使用异喹啉,烷基溴化物,2-羟基苯乙酮或其衍生物,碳酸二甲酯作为绿色试剂和KF /斜发沸石纳米颗粒作为催化剂在水性介质中进行多组分反应,以高收率合成吡咯并异喹啉衍生物在80°C下。的石榴果皮水提取物用作绿色媒体用于合成PG -KF /高收率斜发沸石的纳米颗粒。该PG‐KF /斜发沸石纳米颗粒在这些反应中显示出重要的基本催化作用,从而高产地制备了该产品,并多次使用。此外,为了研究某些合成化合物的抗氧化能力,还采用了二苯基吡咯肼(DPPH)自由基捕获法和三价铁还原能力测试法。反应时间短,产物产率高,催化剂和产物易于分离是该方法的一些优点。
