a simple, mild and high efficient procedure for one pot three component synthesis of 2-amino 4-h chromene derivatives was studied. the reaction was performed in water using aryl aldehydes, malononitrile and resorcinol, phloroglucinol or naphthole in the presence of n-methyl d-glucamine (meglumine) as a green high efficient catalyst. the reaction was studied in thermal, microwave (mw) and ultras...

8 2 ABSTRACT 9 The reaction between m-diphenols (resorcinol, 2-methylresorcinol, 2,5-10 dimethylresorcinol, 3-methylphenol, orcinol, and phloroglucinol) and 2-alkenals (2-11 pentenal and 2-octenal) was studied in an attempt to understand the chemical pathways 12 involved in the scavenging ability of m-diphenols for the 2-alkenals produced as a 13 consequence of lipid oxidation. Phenols reacted ...

Due to the increase in demand for speed, multimedia support and other resources, the wireless world is looking forward for a new generation technology to replace the third generation. This is where the fourth generation wireless communication comes into play. 4G wireless communication is expected to provide better speed, high capacity, lower cost and IP based services. The main aim of 4G wirele...

Coumarins and their derivatives are important classes of heterocyclic compounds whose synthesis has been the focus of attention of many organic and medicinal chemists. Such an interest in these compounds can be attributed to their variety of bioactivities such as, inhibition of platelet aggregation [1], antibacterial [2], anticancer [3], inhibitor of steroid 5αreductase [4] and inhibitor of HIV...
