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/acsami.4c01621
Abstract: The cascade synthesis of pyrroles from nitroarenes is an attractive alternative strategy. However, metal catalysts and relatively high temperatures cover the existing reported catalytic systems for this strategy. The development of nonmetallic heterogeneous catalytic systems… 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.
