Abstract:
3‐(2‐Aryl‐2,3‐dihydro‐benzob]1,4]thiazepin‐4‐yl)chromen‐2‐ones ( 2a, e, f ) and (Z)‐3‐(2,3‐dihydro‐2‐arylbenzob]1,4]thiazepin‐4(5H)‐ylidene)chroman‐2‐ones ( 3a‐f ) have been synthesized by the reaction of 3‐aryl‐1‐(3‐coumarinyl)propen‐1‐ones ( 1a‐f ) with 2‐aminothiophenol in a hot mixture of toluene and acetic acid. Structures of all new compounds and their complete 1H and 13C assignments were achieved applying different one‐ and two‐dimensional nmr experiments in combination with various spectroscopic techniques.
