Gold/Copper Dual-Catalyzed Annulation of Arynes with Phosphites: A Synthetic Strategy for Dibenzophospholes

Organic Letters, Год журнала: 2025, Номер unknown

Опубликована: Апрель 27, 2025

A synthetic approach to dibenzophospholes was developed via the gold- and copper-catalyzed annulation reactions of arynes phosphites. The reaction conditions demonstrated a broad functional group tolerance, enabling synthesis diverse range dibenzophosphole 5-oxides. This method is useful for preparing with unique optical electronic properties.

Assembly of Phospha‐Xanthenes from Functionalized Organophosphines and Arynes through a Formal (4+2) Annulation‐Inspired Cascade

Advanced Synthesis & Catalysis, Год журнала: 2023, Номер 365(22), С. 3849 - 3854

Опубликована: Окт. 18, 2023

Abstract Herein, we report an approach to phospha‐xanthenes from ortho ‐chalcone based organophosphines and arynes. These reactions proceeded through a sequential process consisting of formal [4+2] cycloaddition, arylation, P−OH formation P−C bond cleavage. A gram‐scale preparation chemical conversion were performed demonstrate the synthetic utility this method. Also, possible mechanism was proposed on control experiments.

Synthetic Strategies toward Ortho-3-propanoate Substituted Aryl Phosphonates by Three-Component Coupling Reactions of Arynes, Phosphites, and Acrylates

The Journal of Organic Chemistry, Год журнала: 2024, Номер 89(11), С. 8035 - 8040

Опубликована: Май 28, 2024

Mild, metal-free, and operationally simple three-component coupling reactions involving arynes, phosphites, acrylates have been achieved. The reaction proceeded well with α- or β-substituted acrylates. Additionally, various functional groups were tolerated under these conditions, resulting in diverse
