Intermolecular photoreaction of benzenecarbothioamide with beta-ionone~(#,1)

摘要

Irradiation of benzenecarbothioamide with beta-ionone in benzene gives 1,5,6,7,8,8a-hexahydroquinoline derivative in moderate yield. In a previous paper, we reported that arenecarbothioamides undergo the Paterno-Buchi type reaction with diene conjugated carbonyl compounds to give 2-arylpyridines, 2,6-diarylpyridines, and benzofused pyridines.~2
