A simple and efficient synthesis of aryl and heteroaryl substituted pyrimidines has been developed via initial Knoevenagal, subsequent addition and final cyclization of aldehyde, ethylcyanoacetate and guanidine nitrate. Piperidine has been used as a catalyst. Short reaction time, environment friendly procedure and excellent yields are the advantages of this procedure. All synthesized compounds ...

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...
