The first manganese-catalyzed modified Clauson-Kaas reaction for N-substituted pyrrole synthesis using 2,5-dimethoxytetrahydrofuran with variously substituted aromatic amines has been developed (up to 89% yield). This interesting neat strategy is free from additives including co-catalysts, ligands, and acids. Relatively low cost, environmentally benign, and handy Mn(NO3)2·4H2O is employed as the catalyst under microwave conditions with a very short reaction time (20?min). The above qualities attest to the green nature of this reaction.

A new and efficient methodology to synthesize N-substituted pyrrole derivatives by Clauson Kaas reaction employing Oxone as catalyst was developed. The transformation was performed in acetonitrile under microwave irradiation. This procedure has several advantages such as high yield, clean product formation, and short reaction time.

Moderated and mild way for synthesizing N-substituted pyrrole has been demonstrated herein. No solvents need to be used for this reaction, and instead, reactants themselves acted as a reaction medium. In fact, the reaction is carried out using catalytic amount of Ca(NO3)2.4H2O. The reaction conditions are selective and mild that helped to tolerate a wide variety of functional groups to give the desired products in good chemical yields.

With a strategy of the formation of benzynes by using diaryliodonium salts, a cycloaddition reaction of N-arylpyrroles with benzynes was reported. A wide range of bridge-ring amines with various substituents have been synthesized in moderate to excellent yields (35-96%). Furthermore, with a catalytic amount of TsOH·H2O, these amines can be converted into the corresponding N-phenylamine derivatives easily, which are potentially useful in photosensitive dyes.

Herein, nickel-catalyzed sustainable strategy for the synthesis of N-substituted pyrroles using butene-1,4-diols and butyne-1,4-diols with a series of aryl-, alkyl-, and heteroarylamines is reported. The catalytic protocol is tolerant of free alcohol, halide, alkyl, alkoxy, oxygen heterocycles, activated benzyl, and the pyridine moiety and resulted in up to 90% yield. Initial mechanistic studies involving defined nickel catalyst, determination of rate, and order of reaction including deuterium-labeling experiments were performed for pyrrole synthesis.

A chemoenzymatic cascade process for the sustainable production of pyrroles has been developed. Pyrroles were synthesized by exploiting the previously unexplored aromatizing activity of monoamine oxidase enzymes (MAO-N and 6-HDNO). MAO-N/6-HDNO whole cell biocatalysts are able to convert 3-pyrrolines into pyrroles under mild conditions and in high yields. Moreover, MAO-N can work in combination with the ruthenium Grubbs catalyst, leading to the synthesis of pyrroles from diallylamines/-anilines in a one-pot cascade metathesis-aromatization sequence.
