Multicomponent Coupling

Multicomponent reactions (MCRs) constitute a powerful synthetic tool to generate a large number of small molecules with high atom economy, which thus can efficiently expand the chemical space with molecular diversity and complexity. Aryne-based MCRs offer versatile possibilities to construct functionalized arenes and benzo-fused heterocycles. Because of their electrophilic nature, arynes couple with a broad range of nucleophiles. Thus, a variety of aryne-based MCRs have been developed, the representative of which are summarized in this account.1 Introduction2 Aryne-Based Multicomponent Reactions2.1 Trapping with Isocyanides2.2 Trapping with Imines2.3 Trapping with Amines2.4 Insertion into π-Bonds2.5 Trapping with Ethers and Thioethers2.6 Trapping with Carbanions2.7 Transition-Metal-Catalyzed Approaches3 Strategies Based on Hexadehydro Diels–Alder Reaction3.1 Dihalogenation3.2 Halohydroxylation and Haloacylation3.3 Amides and Imides3.4 Quinazolines3.5 Benzocyclobutene-1,2-diimines and 3H-Indole-3-imines3.6 Other MCRs of Arynes and Isocyanides4 Conclusion

In recent years, the synthesis of quinoline scaffold using various methodological devices has attracted considerable attention in synthetic chemist community. The most feasible method to serve this purpose is Aza-Diels-Alder reaction which provides flexibility and diversity in the synthesis of quinoline decorated with different functionalities over the scaffold. Diversity in this functionality improvises the susceptibility of the quinoline scaffold for various protein targets. This review encompasses multifactorial aspects of Aza-Diels-Alder reaction as well as provides insights into the synthetic schemes for quinoline scaffold.
