Abstract

Arylhydrazonopyridinones

Arylhydrazonothieno[3,4- c]pyridinones

Green chemistry

Microwave irradiation

Ultrasound irradiation

X-ray crystal structure determination

A variety of arylhydrazonopyridinones were prepared via heating cyanoacetamides with ethyl acetoacetate in absence of solvent under reflux conventionally or ultrasound irradiation or in a microwave oven. The formed products 5 and 6 could be readily converted to thienopyridones. Attempted addition of the latter to electron poor olefins afforded only arylhydrazonopyridinones.
