Dual‐Function Cosubstrates Enable Threonine Dehydrogenase‐Driven Chemoenzymatic Pyrrole Synthesis
Angewandte Chemie International Edition, EarlyView.Classical Knorr chemistry meets contemporary biocatalysis. Threonine dehydrogenase generates aminoacetone from l‐threonine, which is directly intercepted in a chemoenzymatic Knorr pyrrole synthesis. A dual‐function β‐dicarbonyl substrate serves as both pyrrole precursor and hydride acceptor for integrated NAD+ recycling, affording substituted pyrroles ...

Tunable electrochemical synthesis of pyrrole-based adsorbents
, 2019 Pyrrole-based adsorbents were developed electrochemically using systems: (i) pyrrole-potassium bromide, (ii) pyrrole-KBr-an anionic surfactant sodium dodecyl sulfate, and (iii) pyrrole-KBr-NaDS-Prussian blue.

Strain-Based Design, Direct Macrocyclization, and Metal Complexation of Thiazole-Containing Calix[3]pyrrole Analogues [PDF]
Coordination chemistry of ring-contracted porphyrins, such as subporphyrin and calix[3]pyrrole, has been largely unexplored due to the synthetic difficulty of their free-base analogues.

Cyclo[4]pyrrole with α–β direct linkages
A cyclo[4]pyrrole bearing pyrrole C(α)–C(β) direct linkages, a contracted porphyrin analogue with no meso-carbon bridge, was synthesized from an oligoketone-related precursor.

Pyrrole Compounds as Food Mutagens
, 1987 The mutagenicity of some pyrrole compounds were studied. Pyrrole compounds tested showed the mutagenicity on bacterial tester strains. Pyrrole and N-methylpyrrole had positive mutagenic activity on the ret-assay with Bacillus subtilis strains H 17 (Ret+)

Biocatalysts for Peptide Geranylation With Linear and Cyclic Prenyl Groups
Angewandte Chemie International Edition, EarlyView.A combination of genome mining, synthetic biology, and biocatalytic assays revealed enzymes that install linear and cyclized prenyl moieties on ribosomally or chemically synthesized peptides. The promiscuity of both enzymes, while being specific for modification of C‐terminal tryptophans, enables enzymatic access to peptide terpenoid hybrids.

Accelerating green heterocyclic synthesis: Convergence of AI, automation, and sustainable chemistry
Bulletin of the Korean Chemical Society, EarlyView.Green heterocyclic synthesis and data‐driven tools such as AI, high‐throughput experimentation, continuous flow, and self‐driving laboratories have developed largely in parallel. This review connects them and asks how green metrics such as E‐factor and PMI might serve as explicit optimization targets rather than post‐hoc measures, toward sustainable ...

Porous Carbon Materials for Carbon Dioxide Capture
Carbon Energy, EarlyView.This work aims to address the current status and challenges associated with the regulation of pore structures, as well as the influence of pore structures on CO2 capture. Systematic quantitative analysis of structure–property relationships, combined with machine learning approaches, can effectively evaluate the contributions of structural ...
