An inimitable illustration of the green-light-induced synthesis of thio-functionalized pyrroles has been established using β-ketodinitriles and thiophenols as the reacting partners and eosin Y as the photocatalyst. Large-scale synthesis and some useful synthetic modifications of the thio-functionalized pyrroles are also demonstrated.
已经使用 β-酮二腈和苯硫酚作为反应伙伴,曙红 Y 作为光催化剂,建立了绿光诱导合成硫代官能化吡咯的独特说明。还展示了硫代官能化吡咯的大规模合成和一些有用的合成修饰。

A series of fused pyrroles were synthesized and tested for their in vivo anti-inflammatory activity. Among 14 examined derivatives, 5 derivatives (1b-e, g and 5b), showed a promising anti-inflammatory activity equivalent to reference anti-inflammatory drugs (indomethacin and ibuprofen). A molecular docking study was conducted to interpret the biological activities of the tested compounds. The docking

An efficient and eco‐friendly protocol for the synthesis of diverse 4,5‐substituted 1H‐pyrrole‐3‐carbonitriles has been developed using commercially available HZSM‐5 and Pd/C as recyclable heterogeneous catalysts with more excellent yields (up to 98 %) than traditional liquids acids, and successfully applied in the practical synthesis of vonoprazan. The conspicuous features of this protocol are higher
