DOI: 10.1007/3715
Abstract: Обзор посвящен опубликованным за последние 10 лет методам синтеза пирролов на основе α,βнепредельных альдегидов. Основным подходом к синтезу этих гетероциклических систем являются многокомпонентные реакции. Участие алифатических, ароматических, α-разветвленных еналей в таких реакциях позволяет получать целевые… read more here.

DOI: 10.1021/jacs.0c03859
Abstract: Herein, we describe an efficient method to prepare polysubstituted pyrroles via a copper-hydride (CuH)-catalyzed enyne-nitrile coupling reaction. This protocol accommodates both aromatic and aliphatic substituents and a broad range of functional groups, providing a variety… read more here.

DOI: 10.1021/jacs.1c04835
Abstract: We present a modular, synthetic entry to polysubstituted pyrroles employing readily available 2,5-dihydrothiophenes. Ring-opening of the heterocycle provides access to a panel of 1,3-dienes which undergo pyrrole formation in the presence of inexpensive chloramine-T trihydrate.… read more here.

DOI: 10.2174/1385272824666200228121627
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… read more here.
