One-pot three component synthesis of 2-amino-4H-chromenes under green and high efficient conditions

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...

p-Toluenesulfonic acid catalyzed rapid and efficient protocol for one-pot synthesis of α-amino nitriles

A simple, rapid and efficient practical method for one-pot synthesis of α-amino nitriles has been achieved by a threecomponent condensation of carbonyl compounds, amines and trimethylsilyl cyanide in the presence of p-toluenesulfonic acid (p-TsOH) as a catalyst at ambient temperature. Operational simplicity, economic consideration, high yield, short reaction time and low toxicity are the key fe...
