Abstract

4-Aryl-2-(3-chromonyl)-2,3-dihydro-1,5-benzothiazepines 3a-g have been synthesized by the reaction of 2-aminothiophenol (1) and 3-(3-oxo-3-arylpropenyl)chromen-4-ones 2a-g in hot toluene in the presence of acetic acid. 1,5-Benzothiazepines 3a,b,d,e have been converted into 3-acetyl-2,3-dihydrobenzothiazoles 4a,b,d,e under acetylating conditions.
