Abstract
Commercially available magnesium perchlorate has been found to be a highly efficient catalyst for the reaction of 1,3-diarylprop-2-enones with 2-aminothiophenol leading to the synthesis of 2,3-dihydro-1,5-benzothiazepines in high yields and in short times.
Key words
1,5-benzothiazepines - 2-aminothiophenol - 1,3-diarylprop-2-enones - magnesium perchlorate - catalyst - chemoselective
