Abstract:


β-Amino-α,β-enones or β-enamino carbonyl compounds are versatile synthons intermediates for the construction of various bio-active heterocyclic compounds and have been established as multipurpose synthetic precursors in organic syntheses and in pharmaceutical developments. In this work, we will discuss the different synthetic routes to obtain β−amino−α,β-enones or β-enamino carbonyl compounds, their reactions, and their utility in the construction of organic frameworks and heterocyclic ring systems. Structurally, β- amino-α,β-enones are attractive intermediates that syndicate the ambident behaviours of nucleophilicity and electrophilicity of enones at the same time. β-amino-α,β-enones have been known as acceptors in both 1,2- and 1,4- additions that make them good intermediate compounds for annulation to different heterocycles.

Keywords:

Enaminones, nitrogen nucleophiles, heterocycles, synthesis, β-enamino, β-amino-α, β-enones.
