چکیده
|
An efficient and rapid method was developed for the synthesis of c3-pyranopyrazole-substituted coumarins from one-pot five-component reaction of β-keto ester, hydrazine, o-hydroxy aromatic aldehydes, 6-methyl, 4-hydroxy pyranone and aromatic aldehyde in the presence of tri-ethylamine in solvent-free conditions. the microwave-assisted method reported herein offers advantageous shorter reaction times, higher yields and cleaner reaction compared with conventional heating methods.
