Silver‐catalyzed pyrrole synthesis: An overview

Abstract

The pyrrole structure is a pivotal unit of many natural products, bioactive compounds, and organic materials. Pyrrole derivatives are commonly used as intermediates in the synthesis of various agrochemicals, pharmaceuticals, dyes, and other synthetic organic compounds. In organic synthesis, silver catalysis has been of great interest and has spread widely due to unique reactivity, selectivity, stability, and recyclability in catalytic reactions. Over the past decade, numerous synthetic strategies have been established for the facile and effective synthesis of pyrrole derivatives through silver catalysis. This review focuses exclusively on the synthesis of pyrroles via silver catalysis, covering literature until the middle of 2020.

Volatile Compounds of Algal Biomass Pyrolysis

“…Devolatises at 329 • C, in endemic microalgae. It derivatives are commonly used as intermediate products in the synthesis of diverse agrochemicals, pharmaceutical products, dyes and other synthetic organic compounds [73]. It is also obtained from the hydropyrolysis of Cyanobacteria green algae, of the Oscillatoria genus [74].…”

Catalyst‐free one‐pot three‐component rapid synthesis of polysubstituted pyrroles by liquid‐assisted grinding

“…In view of the significance of polysubstituted pyrroles, considerable efforts have been devoted to develop concise and efficient methods for the synthesis of these heterocycles [15,16]. For example, Zhou and co-workers reported an electro-oxidative approach for the preparation of polysubstituted pyrroles by using 1,3-dicarbonyl compounds and primary amines as substrates [17].…”

AgNTf2-Catalyzed Regioselective C–H Alkenylation of N,N-Dialkylanilines with Ynamides

“…In the past few decades, many useful transformations have been achieved in this field . Among them, silver catalysts have attracted significant interest due to their unique alkynophilicity, along with nontoxicity, relatively low price, and stability . Based on the selective coordination of silver salts with a triple bond to form silver complex, a number of silver catalyzed reactions involving alkynes have been reported .…”
