Multicomponent Heteroarylphosphorothiolation of Alkenes for Accessing β‐Phosphorothiolated Quinoxalinones

Advanced Synthesis & Catalysis, Journal Year: 2024, Volume and Issue: 366(12), P. 2758 - 2763

Published: April 24, 2024

Abstract Herein, we present a (NH 4 ) 2 S O 8 mediated difunctionalization reaction of aryl alkenes with quinoxalinones and P(O)SH compounds. This method enables the synthesis various phosphorothioate‐containing quinoxalin‐2(1 H )‐one derivatives (46 examples) in 37–79% yields. The is compatible range functional groups easily adaptable to large‐scale synthesis. Preliminary studies suggest involvement phosphorothioate radicals these transformations.
