Abstract
Ethyl 3-dimethylamino acrylates 1a-c have been used as starting materials t o develop an efficient and mild solvent-free preparation of new ethyl beta -hydrazino acrylates 3a-h and 1,2-dihydropyrazol-3-ones 4a-c in good yields from a variety of hydrazines 2a-d by transamination and aza-annulation rea ctions under microwave irradiations.
