ZnCl2-Catalyzed Four-Component Domino Reaction for One-Pot Eco-Safe and Convenient Synthesis of Polyfunctionalized Dihydro-2-oxopyrroles at Ambient Temperature

Abstract

В присутності екологічно безпечного і ефективного каталізатора Фріделя-Крафта ZnCl2 проведено одноступеневий чотирикомпонентний синтез полізаміщеного дигідро-2-оксопіролу за кімнатної температури з викорис- танням діалкилацетилендикарбоксилату, формальдегіду та амінів (ароматичних та аліфатичних). Показаний ряд переваг такого синтезу: легкість, дешевизна, екологічно безпечний каталізатор, короткий час реакції, високі виходи, легке оброблення (тільки звичайна фільтрація) та простота експ- луатації. Визначено характеристику одержаних продуктів за допомогою Фур‘є- та ЯМР-спектроскопії. In this study, ZnCl2 was applied as an environmentally friendly and efficient Lewis acid catalyst for the one-pot four-component synthesis of polysubstituted dihydro-2-oxopyrroles from the reaction between dialkyl acetylenedicarboxylate, formaldehyde and amines (aromatic and aliphatic) at ambient temperature. This methodology has a number of advantages such as use of inexpensive, eco-safety of catalyst, short reaction times, high yields, easy work-up (just simple filtration), and simplicity of operation. All products are characterized by comparison of FT-IR and 1H NMR spectroscopic data.
