many esters and amide derivatives of KYNA are synthesized via coupling reaction or multi-step synthesis using different organic or metallic catalysts. Herein, we developed a novel one-pot, catalyst-free, convenient synthesis of KYNA ethyl esters using aniline and diethyl acetylene dicarboxylate in DMF under heating. We also explored the synthesis of KYNA and KYNA amide derivative in a simple manner with

A practical and efficient strategy has been described for the preparation of 4-quinolone derivatives. Using commercially available diethyl acetylenedicarboxylate and aromatic amines as starting materials, the synthetic protocol has been achieved and afforded the product via hydroamination at room temperature followed by PPA-catalyzed intramolecular ring closure. The products can be easily obtained in high yields. Conditions and mechanism of the reaction have also been investigated. This protocol is environmentally friendly and transition-metal-free, with advantages including short reaction time, convenient operation, and mild reaction conditions. (C) 2015 Elsevier Ltd.
