We describe herein a fundamentally new visible light-driven homolytic C-C bond breaking mode for the generation of acyl radicals from C2-acyl-substituted benzothiazolines. The reactive species can be used as versatile synthons for formal radical alkylatio

o-Aminothiophenol reacted with ketones and β-keto esters in the presence of alumina under mild and solvent-free conditions to afford the corresponding benzothiazolines in high yields. Alumina can be reused for subsequent reactions without any loss of the

Reaction of 2-aminophenol and 2-aminothiophenol with 1-phenyl-1,2-propanedione yields a mixture of both possible isomeric benzo[1,4]oxazines and benzothiazolines which were characterized by NMR spectroscopy. In addition, the structures for 3-methyl-2-phenyl-2H-benzo[1,4]-oxazin-2-oI and 1-(2-phenyl-2,3-dihydro-benzothiazol-2-yl)-ethanone were established by X-ray diffraction analysis.
