"One Pot" Synthesis of 1,5-Diaza-2,3,6,7-Thetrahydro-4-Methyl-Phenanthrene-4,8-Dione From Corresponding Bis-Beta-Amino Acid

One Pot Synthesis of Alpha-Aminonitrile and Alpha-Amino Acid From Schiff Bases

Addition of Potassium cyanide to a mixture of Schiff base and lithium perchlorate afforded a-aminonitriles in high yields. Addition of potassium cyanide to a methanolic solution of Schiff base and phosphoric acid afforded a-aminonitriles. When the reaction mixture was refluxed it gave a-amino acids in high yields.

Sulfuric Acid Functionalized Magnetic Nanocatalyst for One-pot Green Synthesis of 2,3-Dihydroquinazolin-4 (1H) -ones

Sulfuric acid functionalized magnetic nanocatalyst (SAMNC) has been prepared as an efficientacidic and applied in the one-pot preparation of 2,3-dihydroquinazolin-4 (1H) -one derivatives.This catalyst has been characterized by FT-IR, SEM, and VSM. According to the obtainedresults, including time, yield and recyclability, SAMNC could be considered as an efficient catalystfor organic transformati...

Efficient one-pot synthesis of 6-amino-4-aryl-5-cyano-2-methyl-4H-pyran-3-carboxylates catalyzed by nano MgO in water

Water is a versatile solvent in many ways, and in this sense performing organic reactions in this medium is now of great interest. The one-pot reaction of ethyl acetoacetate or benzyl acetoacetate, with benzaldehydes and malononitrile to provide some novel 6-amino-4-aryl-5-cyano-2-methyl-4H-pyran-3-carboxylates has been performed over nano MgO with high performance in water as a green solvent a...
