Catalytic synthesis method of 1,3-dicarbonyl compounds

The invention discloses a catalytic synthesis method of 1,3-dicarbonyl compounds. According to the catalytic synthesis method, with the participation of sodium carbonate, aniline compounds and ethyl bromide difluoroacetate are subjected to defluorination

Synthesis of functionalized β-enamino compounds by carbon-fragment transfer reaction of C(2)-substituted imidazolidines with amines

The substituted imidazolidines (2, 3, 5) and a ring-opening product, N,N,N'-trisubstituted 2-methyl-ethylenediamines (4), derived from addition of the carbon anions to 1-tosyl-3,4-dimethylimidazolinium iodide (1), were utilized to transfer substituted one-carbon units to various amines to yield a series of functionalized β-enamino compounds.

Solvent-free synthesis of quinolone derivatives

Quinolones can be prepared in a three step procedure from triethylorthoformate and activated methylene derivatives leading to alkoxymethylenemalonates followed by reaction with aromatic amines and finally a cyclization. All the reactions were carried out under solvent-free conditions possibly under microwave activation with benefits for the first step.
