Abstract
The following review provides up to date information about the recent progress in synthetic approaches and chemical reactivities to alpha-(arylhydrazono)-beta-ketoaldehydes, mainly using N,N-dimethyl-beta-ketoenamines as an efficient starting material. These a (arylhydrazono)-beta-ketoaldehydes have assured to be of biological interest and furnish an inlet to a new class of biologically active heterocyclic compounds for biomedical implementations. The data published until the end of 2017 have been covered.
