Recent developments in multicomponent synthesis of structurally diversified tetrahydropyridines

摘要

Tetrahydropyridines (THPDs) have been recognized as a major constituent of naturally occurring alkaloids. Being heterocyclic nitrogenous compounds, they therefore display robust biological and pharmacological profiles. In this context, they are fascinating synthetic targets in synthetic chemistry and as a consequence of this their synthesis through simple and convenient tactics has emerged as an important and challenging task. To meet such challenge, multicomponent reactions (MCRs) are employed as an excellent tool for achieving compounds containing complex diversity in single step and production of their vast libraries. This review represents the advancement made in the field of multicomponent synthesis of THPDs and their derivatives of the last few years.
