Abstract
Abstract A series of new 3-benzyl-1,10-diaryl-4 H ,10 H -thieno[3,4- c ][1,5]benzothiazepines has been synthesised regioselectively from the reaction of 5-aryl-2,4-bis(arylmethylidene)dihydro-3-thiophenones with o -aminothiophenol in the presence of acetic acid. This transformation presumably occurs via a tandem Michael addition–condensation–isomerisation sequence.
