Abstract
A new metal-free synthesis of pyrrole from allyl ketone and amine has been established. The reaction proceeds via an thiolative activation of the C-C double bond with dimethyl(methylthio)sulfonium trifluoromethanesulfonate, followed by a nucleophilic ring-opening addition of primary amine to the generated episulfonium intermediate, and then an internal condensation and aromatization. This mild procedure provides a novel strategy to the construction of substituted pyrroles through a formal [4 + 1] cycloaddition reaction.

Abstract
A gold-catalysed cycloisomerization of 1,5-diynes is described, which offers a selective approach to access 1,3,4-trisubstituted pyrroles. In this reaction, the cationic gold catalyst activates the ynamide moiety, initiating the cycloisomerization to produce the pyrrole core, and H2O acts as an external nucleophile to trap the vinyl cationic species, thus leading to the formation of 1,3,4-trisubstituted pyrroles with high selectivity.

Abstract
Herein, the copper-catalyzed annulation of enaminones with alkynyl esters for the facile synthesis of different pyrroles with a 2,3,4,5-tetrasubstituted structure has been developed. With Cu(OAc)2 as the only catalyst, the tunable synthesis of 2-vinyl and 2,3-dicarboxyl-functionalized pyrroles has been achieved by using terminal and internal alkynyl esters, respectively. The synthesis of 2-vinyl pyrroles represents the first example accessing 2-vinyl substituted pyrroles via direct cascade reactions involving vinylation and pyrrole ring formation.

Abstract
![]()
The combination of
nucleophilic nitrenoids and π-acid catalysis
has emerged as a powerful tool in heterocycle synthesis. Accessing
more varied heterocycle-substitution patterns by maintaining the same
reaction pathways across different alkynes remains a challenge. Here
we show that Au(I) catalysis of isoxazole-based nitrenoids with alkynyl
thioethers provides controlled access to (3 + 2) annulation by a regioselective
addition β to the sulfenyl group. The reaction with isoxazole-containing
nitrenoids delivers sulfenylated pyrroles and indoles as single regioisomers
bearing useful functional groups and structural variety.

Abstract
This review article features selected examples on the synthesis of functionalized pyrroles that were reported between 2014 and 2019. Pyrrole is an important nitrogen-containing aromatic heterocycle that can be found in numerous compounds of biological and material significance. Given its vast importance, pyrrole continues to be an attractive target for the development of new synthetic reactions. The contents of this article are organized by the starting materials, which can be broadly classified into four different types: substrates bearing π-systems, substrates bearing carbonyl and other polar groups, and substrates bearing heterocyclic motifs. Brief discussions on plausible reaction mechanisms for most transformations are also presented.

Abstract
Pyrroles are the most prevalent heterocyclic compounds, which are present as the basic cores in
many natural products, such as vitamin B12, bile pigments like bilirubin and biliverdin, the porphyrins of
heme, chlorophyll, chlorins, bacteriochlorins, and porphyrinogens. The biological activities of compounds
having pyrrole analogs include antimicrobial (antibacterial, antifungal), anti-cancer (anti-cytotoxic, antimitotic),
anti-tumor, anti-hyperlipidemic, anti-depressant, anti-inflammatory, antihyperglycemic, antiproliferative,
anti-HIV and anti-viral activities. Accordingly, significant attention has been paid to develop competent
methods for the synthesis of pyrroles with improved yields in short times. This review gives an overview of
different methods for the synthesis of pyrrole using easily available precursors using the following routes.
Synthesis of monosubstituted pyrrole using 2,5-dimethoxyfuran
Synthesis of pyrrole using dialkylacetylene dicarboxylate
Synthesis of pyrroles using β-ketoester
Synthesis of pyrrole using 1,2-dicarbonyl compounds
Synthesis of pyrroles using 1,3-dicarbonyl compounds
Synthesis of pyrroles using 1,3-dicarbonyl, amine, nitro and aldehyde group
Synthesis of pyrroles using 1,4-dicarbonyl compound and amines
Synthesis of pyrrole using enones
Synthesis of pyrroles using moieties having acetylene group

Abstract
Catalytic transformations involving metal carbenes are considered one of the most important aspects of homogeneous transition metal catalysis. Recently, gold-catalyzed generation of gold carbenes from readily available alkynes represents a significant advance in metal carbene chemistry. This Review summarizes the advances in the gold-catalyzed nitrene-transfer reactions of alkynes with nitrogen-transfer reagents, such as azides, nitrogen ylides, isoxazoles, and anthranils, and gold-catalyzed carbene-transfer reactions, involving oxygen atom-transfer reactions of alkynes with nitro compounds, nitrones, sulfoxides, and pyridine N-oxides, through the presumable α-imino gold carbene and α-oxo gold carbene intermediates, respectively. Gold-catalyzed processes are reviewed by highlighting their product diversity, selectivity, and applicability, and the mechanistic rationale is presented where possible.

Abstract
:
Pyrrole derivatives are nitrogen-containing heterocyclic compounds and widely
distributed in a large number of natural and non-natural compounds. These compounds
possess a broad spectrum of biological activities such as anti-infammatory, antiviral, antitumor,
antifungal, and antibacterial activities. Besides their biological activity, pyrrole derivatives
have also been applied in various areas such as dyes, conducting polymers, organic
semiconductors.
:
Due to such a wide range of applicability, access to this class of compounds has attracted
intensive research interest. Various established synthetic methods such as Paal-Knorr,
Huisgen, and Hantzsch have been modified and improved. In addition, numerous novel
methods for pyrrole synthesis have been discovered. This review will focus on considerable
studies on the synthesis of pyrroles, which date back from 2014.

Abstract
A novel approach has been constructed for the synthesis of two types of 2-amino-4-coumarinyl-5-arylpyrroles (ACAPs, 5 and 6) through a cascade reaction and a metal-free catalyzed aerobic oxidation reaction of arylglyoxal monohydrates 1, 1,1-enediamines (EDAMs) 2 and 3, and 4-hydroxy-2H-chromen-2-ones 4 via multicomponent reactions to produce the target compounds with good to excellent yields. Specifically, hydroxyl-substituted 2-amino-4-coumarinyl-5-arylpyrroles, that is, 2-amino-4-coumarinyl-5-aryl-6-hydroxylpyrroles (ACAHPs) 6, were obtained by metal-free aerobic oxidation in 1,4-dioxane at simple reflux for approximately 10 h. As a result, ACAHPs 6 have been produced without metal catalysts or traditional oxidizing agents. This method represents a route to obtain the novel ACAPs in an environmentally friendly, concise, rapid, and practical manner with potential biological activity of the product.

Abstract
6π electrocyclization has attracted interest in organic synthesis because of its high stereospecificity and atom economy in the construction of versatile 5-7-membered cycles. However, examples of asymmetric 6π electrocyclization are quite scarce, and have to rely on the use of chiral organocatalysts, and been limited to pentadienyl-anion- and triene-type 6π electrocyclizations. Described herein is a zinc-catalyzed formal [4+3] annulation of isoxazoles with 3-en-1-ynol ethers via 6π electrocyclization, leading to the site-selective synthesis of functionalized 2H-azepines and 4H-azepines in good to excellent yields with broad substrate scope. Moreover, this strategy has also been used to produce chiral 2H-azepines with high enantioselectivities (up to 97:3 e.r.). This protocol not only is the first asymmetric heptatrienyl-cation-type 6π electrocyclization, but also is the first asymmetric reaction of isoxazoles with alkynes and the first asymmetric catalysis based on ynol ethers.

Abstract
The detailed mechanisms of gold(i)-catalyzed annulations of propiolates with substituted and unsubstituted isoxazoles were investigated by DFT calculations. A unified rationale for the formation of the key seven-membered heterocyclic intermediate was proposed through initial chemoselective N-attack of isoxazole followed by sequential generation of an unprecedented 2H-azirine-containing intermediate, 6π electrocyclization and ring expansion. Subsequent substrate-dependent transformations were rationalized to generate the divergent products. The origins of the chemo- and regio-selectivities coupled with the factors responsible were addressed.

Abstract
Gold-catalyzed bicyclic annulations of 4-methoxy-1,2-dienyl-5-ynes with isoxazoles afford indolizine derivatives; the reaction mechanism involves alkyne attack on a gold π-allene to yield a vinyl gold carbene.
Gold-catalyzed bicyclic annulations of 4-methoxy-1,2-dienyl-5-ynes with isoxazoles afford indolizine derivatives with a structural rearrangement. The mechanism of these new annulations does not involve α-imino gold carbenes generated from gold π-alkyne intermediates. We postulate alkyne attack on gold π-allenes, yielding vinyl gold carbenes. These newly generated carbenes react with isoxazole derivatives to yield Z-3-imino-2-en-1-als, further enabling sequential cyclizations to deliver indolizine derivatives in two distinct classes.
