چکیده
In regard to biological properties, the pharmacophoric quinone group receives great attention due to its extensive use and its presence in compounds with confirmed antitumour, molluscicidal, leishmanicidal, anti-inflammatory and antifungal activities,1-2 as well as its industrial applications and their potential as intermediates in the synthesis of heterocyclic compounds. Lawsone is a p-naphthoquinone containing an enol group, which is susceptible to a multicomponent Mannich reaction.In this study, environmentally friendly one-pot protocol was developed for the first synthesis of aminonaphthoquinones derived from 2-hydroxy-1,4-naphthoquinone (lawsone) via a multicomponent Mannich reaction in aqueous media using a catalytic amount of L-proline in refluxing ethanol (Fig.1)The main advantages of the present synthetic protocol are eco-friendly catalyst, easy reaction work-up procedure and precedent some new derivative compounds. The system chosen for the multicomponent Mannich reaction is nontoxic and extremely inexpensive, which aligns with the concept of green chemistry.کلیدواژه ها

اطلاعات بیشتر در مورد COI
COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
