The following review provides up to date information about the recent progress
in synthetic approaches and chemical reactivities to α-(arylhydrazono)-β-ketoaldehydes,
mainly using N,N-dimethyl-β-ketoenamines as an efficient starting material. These α -
(arylhydrazono)-β-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.
