Rhodium-Catalyzed C4-Selective C–H Alkenylation of 2-Pyridones by Traceless Directing Group Strategy
作者:Sunit Hazra、Koji Hirano、Masahiro Miura
DOI:10.1021/acs.orglett.1c00050
日期:2021.2.19
A rhodium-catalyzed C4-selective C–H alkenylation of 3-carboxy-2-pyridones with styrenes has been developed. The carboxylic group at the C3 position works as the traceless directing group, and the corresponding C4-alkenylated 2-pyridones are obtained exclusively with concomitant decarboxylation. Unlike the reported procedures, the exclusive C4 selectivity is uniformly observed even in the presence
