Electro-Organic Synthesis: An Efficient Method for the Preparation of Nanosized Particles of Phthalazine Derivatives via One-Pot Multicomponent Reactions

electro-organic synthesis: an efficient method for the preparation of nanosized particles of phthalazine derivatives via one-pot multicomponent reactions

aza heterocyclic compounds are major interest for organic chemists because of their mainly pharmacological activities and clinical applications such as antianxiety, antitumor, anticonvulsant, cardiotonic and vasorelaxant. this contribution describes an electrochemical approach for the preparation of nanosized particles of phthalazine in high yields and very short reaction time. the method is ba...

Synthesis of Phosphorus Derivatives via Multicomponent Reactions

Stable derivatives of oxaphosphaphenanthrenes were prepared using multicomponent reactions of 3-bromo-2-naphthol, dialkyl acetylenedicarboxylate and trimethyl or triphenyl phosphite under microwave conditions with good yields.

Nanocrystalline TiO2 as an efficient and reusable catalyst for the one-pot synthesis of polyhydroquinolien derivatives via Hantzsch reaction

An efficient synthesis of polyhydroquinoline derivatives was reported via four-component coupling reactions of aldehydes, 1,3-dicarbonyl ketones (dimedone or 1,3-cyclohexanedione), ethyl acetoacetate or methyl acetoacetate and ammonium acetate in the presence of a catalytic amount of nanocrystalline TiO2 under solvent free conditions. The reported method is mild, rapid and has the advantages su...
