Synthesis of quinolin-2-ones by an intramolecular Knoevenagel condensation and by tandem Michael–Knoevenagel heterocyclization
摘要:
The synthesis of 2-(N-R-amino)- and 2-(N-vinylcarbonylamino)acylbenzenes has been carried out and their heterocyclization into quinolin-2-ones under the action of sodium ethylate has been studied.
