Methyl Acetoacetate: A Useful Reagent in Multicomponent Reactions
Publication History
Publication Date:
17 September 2009 (online)
Introduction
Methyl acetoacetate is considered as a model β-keto ester, and widely used in various multicomponent reactions for the creation of diverse molecular scaffolds. The dawn of methyl acetoacetate as an important multicomponent substrate began in 1982 by the discovery of Hantzsch’s dihydropyridine synthesis. [¹] The reagent exhibits interesting reactivity pattern in multicomponent reactions depending on the reaction conditions, type of reactions, and involved catalysts. The highly synthetic potential of this easily accessible reagent has found numerous applications, especially in the synthesis of complex heterocyclic structures. [²] An overview of the different reactivity of this versatile substrate in multicomponent reaction is presented below.
