What do we know about multicomponent reactions? Mechanisms and trends for the Biginelli, Hantzsch, Mannich, Passerini and Ugi MCRs
TL;DR: The aim of this review is to highlight what the authors already know about the mechanisms associated with these MCRs and the evidence supporting the proposed reaction pathways.
Journal ArticleDOI
Facts, Presumptions, and Myths on the Solvent-Free and Catalyst-Free Biginelli Reaction. What is Catalysis for?
Haline Gerica de Oliveira Alvim,Tatiani B. Lima,Aline L. de Oliveira,Heibbe C. B. de Oliveira,Fabricio Machado Silva,Fabio C. Gozzo,Roberto Y. Souza,Wender A. Silva,Brenno A. D. Neto +8 more
TL;DR: The crucial role of catalysis, solvent effects, mechanisms, kinetics, facts, presumptions, and myths associated with the Biginelli reaction are discussed to avoid current and future confusion and to stimulate new approaches.
Journal ArticleDOI
Ionic Liquid Effect over the Biginelli Reaction under Homogeneous and Heterogeneous Catalysis
Haline Gerica de Oliveira Alvim,Tatiani B. Lima,Heibbe C. B. de Oliveira,Fabio C. Gozzo,Julio L. de Macedo,Patrícia V. Abdelnur,Wender A. Silva,Brenno A. D. Neto +7 more
TL;DR: In this article, metal-containing ionic liquids were evaluated as the catalysts with reasonable results (homogeneous systems) for the Biginelli synthesis of 3,4-dihydropyrimidin-2(1H)-one (DHPMs).
Journal ArticleDOI
Task-specific ionic liquid incorporating anionic heteropolyacid-catalyzed Hantzsch and Mannich multicomponent reactions. Ionic liquid effect probed by ESI-MS(/MS)
Haline Gerica de Oliveira Alvim,Giovana A. Bataglion,Luciana M. Ramos,Aline L. de Oliveira,Heibbe C. B. de Oliveira,Marcos N. Eberlin,Julio L. de Macedo,Wender A. Silva,Brenno A. D. Neto +8 more
TL;DR: A task-specific ionic liquid with a Bronsted acid (1-(3-sulfopropyl)-3-methylimidazolium hydrogen sulfate, namely MSI ) bearing an anionic heteropolyacid derivative ([PW 12 O 40 ] 3−, namely PW ) were used as an efficient catalyst for the three-component Mannich and Hantzsch reactions as discussed by the authors.
Journal ArticleDOI
Heteropolyacid-Containing Ionic Liquid-Catalyzed Multicomponent Synthesis of Bridgehead Nitrogen Heterocycles: Mechanisms and Mitochondrial Staining.
Haline Gerica de Oliveira Alvim,José R. Corrêa,José Antonio Fagundes Assumpção,Wender A. Silva,Marcelo O. Rodrigues,Julio L. de Macedo,Mariana Fioramonte,Fabio C. Gozzo,Claudia C. Gatto,Brenno A. D. Neto +9 more
TL;DR: The current manuscript describes the use of a heteropolyacid-containing task-specific ionic liquid, supported in imidazolium-based ionic liquids, as the catalyst for an efficient multicomponent synthesis of hexahydroimidazo[1,2-α]pyridine derivatives.
