The tridentate amino ether ligands 1 and 14 were developed through systematic structural modification of the bidentate diether ligand 2. The reaction of thiophenol with methyl crotonate was catalyzed by 14 and lithium thiophenolate to afford (S)-methyl 3-

Optically active 2,3-dihydro-1,5-benzothiazepin-4(5H)-ones (14-17) have been synthesized via resolution and chemical transformation of nitrocarboxylic acids 6-9.Starting from the latter various optically active substances have been synthesized as well.Optical purity was checked by NMR spectroscopy. - Keywords: Resolution; Optical purity; Optically active benzothiazepines
