Tuneable access to indole, indolone, and cinnoline derivatives from a common 1,4-diketone Michael acceptor

Synthesis, Biological evaluation and Comparative Study of Some Cinnoline Derivatives

In medicinal chemistry nitrogen containing heterocycles are the most important compounds which show various biological activities. The cinnoline are nitrogenous derivatives and found to elicit many pharmacological actions like anti-hypertensive, antithrombotic, antihistamine, antileukemic, CNS activity, anti tumor, antibacterial and antisecretory activity. We planned to synthesis new series of ...

Convenient One-pot Access to Pyrano[2,3-d]pyrimidine Derivatives via a CuCl2.2H2O Catalyzed Knoevenagel-Michael Addition Reaction in Water/Ethanol Media

Convenient procedure for the synthesis of corresponding pyrano[2,3-d]pyrimidine derivatives were developed via one-pot three-component reaction of aryl aldehyde derivatives, malononitrile with barbituric acids in the presence of copper (II) chloride dihydrate (CuCl2.2H2O) as highly efficient Lewis acid catalyst. This protocol has advantages such as readily and inexpensive catalyst, high reactio...

the aesthetic dimension of howard barkers art: a frankfurtian approach to scenes from an execution and no end of blame

رابطه ی میانِ هنر و شرایطِ اجتماعیِ زایش آن همواره در طولِ تاریخ دغدغه ی ذهنی و دل مشغولیِ اساسیِ منتقدان و نیز هنرمندان بوده است. از آنجا که هنر در قفس آهنیِ زندگیِ اجتماعی محبوس است، گسترش وابستگیِ آن با نهاد ها و اصولِ اجتماعی پیرامون، صرفِ نظر از هم سو بودن و یا غیرِ هم سو بودنِ آن نهاد ها، امری اجتناب ناپذیر به نظر می رسد. با این وجود پدیدار گشتنِ چنین مباحثِ حائز اهمییتی در میان منتقدین، با ظهورِ مکتب ما...

Michael addition of Pyrrole and indole to α,β- unsaturated compounds in the Presence of oxalic acid

A Simple and efficient method for Michael addition of pyrrole and indole to α,β- un saturated compounds has been developed in the presence of oxalic acid under refluxing reaction condition was achieved.
