Abstract Sodium fluoride catalyzed Friedlander condensation of 2-aminonicotinaldehye with various carbonyl compounds containing α-methylene group in the solid state furnished corresponding 1,8-naphthyridines. The reaction proceeds efficiently at room temperature in high yields and in a state of excellent purity.

A facile and efficient AgI-catalytic approach is reported for the first time to synthesize β-oxoamides from β-oxo esters a with broad substrate scope in good to excellent yields. Crossover and in situ NMR studies confirmed that the reaction occurred through a new pathway and not by the traditional condensation reaction. The key advantages of this method are the readily available starting materials

double isocyanide insertionreaction of acetamides with isocyanides has been developed for the synthesis of pyrrolin-2-one derivatives. A wide range of acetamides bearing various functional groups are compatible with this reaction system by utilizing Ni(acac)2 as a catalyst. In this transformation, isocyanide could serve as a C1 connector and insert into the inactive Csp3–H bond, representing an effective

A series of novel 5‐phenyl‐[1,2,4]‐triazolo[4,3‐a]quinoline derivatives was synthesized by the cyclization of 2‐chloro‐4‐phenyl‐1,2‐dihydronaphthalene with formohydrazide. The starting material 2‐chloro‐4‐phenyl‐1,2‐dihydronaphthalene was synthesized from ethyl‐3‐oxo‐3‐phenylpropanoate and substituted aniline. Their anticonvulsantactivities were evaluated by the maximal electroshock (MES) test and

have been synthesized via the three-component domino reaction of glutaraldehyde and malononitrile with a series of beta-ketoamides under microwave irradiation conditions in the presence of a catalytic amount of Et3N (10 mol%). This reaction represents the first reported process for the facile conversion of a beta-ketoamide to a hydroisoquinoline via a C-N bond cleavage reaction without the need for
