[ 1 ] - Mefenamic acid as Environmentally Catalyst for Threecomponent Synthesis of Dihydropyrano [2,3-c]Chromene and Pyrano[2,3-d]Pyrimidine Derivatives
Pills of Mefenamic acid were employed as effective catalysts in the three component reaction of aromatic aldehydes, malononitrile, as well as 4-hydroxycoumarin or barbituric acid in aqueous solution, using reflux conditions in order to synthesize derivatives of dihydropyrano[2,3-c]chromene and pyrano[2,3-d]pyrimidine, correspondingly. Among the benefits of this technique, ...
[ 2 ] - Synthesis of Arylidene (thio)barbituric Acid Derivatives using Bentonite as a Natural and Reusable Catalyst in Green Media
Known as a Lewis acid which acts as a natural catalyst, bentonite can be used to produce several arylidene (thio) barbituric acid derivatives through conducting a Knoevenagel reaction between aromatic aldehydes and (thio) barbituric acid. Water is considered as the medium for this reaction and the results are at arange of good to excellent over a reasonable reaction time. This method i...
[ 3 ] - تهیه یک سری جدید از مشتق‌های کومارین در حضور نانوچندسازه Ti–Al/Al2O3 و بررسی ویژگی ضدباکتری آن‌ها
با توجه به اهمیت مشتق‌های کومارین و بهویژه پیرانوکرومن‌ها به دلیل داشتن ویژگی متفاوت شیمیایی و زیستی در این پژوهش، مشتق‌های پیرانو(h-3،2) کومارین از واکنش بنزالدهید و مشتق‌های کرومن در حضور نانوچندسازه Ti–Al/Al2O3 به‌عنوان کاتالیست و در حلال متانول تهیه شد. فراورده‌های به‌دست‌آمده با طیفسنجیهای FTIR، 1H NMR و 13C NMR شناسایی شدند. پس از شناسایی، ...
