2-Pyridone Ring Formation through the Photoreaction of Arenecarbothioamides with Unsaturated Carboxylic Acids
摘要:
Irradiation of arenecarbothioamides with 2,4-hexadienoic acid in benzene gives 2-pyridone derivatives in moderate yields. The corresponding benzo-fused 2-pyridone derivative was also obtained by use of o-vinylbenzoic acid as dienoic acid equivalent.
