Rh(III)-Catalyzed Regioselective C(sp2)-H alkenylation of isoquin-olones with methoxyallene: A Facile Access to aldehyde bearing iso-quinolones

Organic & Biomolecular Chemistry, Journal Year: 2024, Volume and Issue: 22(32), P. 6612 - 6616

Published: Jan. 1, 2024

A simple and rapid access to isoquinolone aldehyde scaffolds has been established by a rhodium-catalyzed reaction between methoxyallene that forges alkenylation in an explicit regioselective manner. Herein, serving as acrolein equivalent results execution of this unique functionalization. Furthermore, the compatibility with complex molecules underscores significance developed protocol. The mechanistic proposal for transformation was consistent kinetic studies several control reactions.
