Synthesis of 1,4-Thiazepine Derivatives Having Angiotensin-Converting Enzyme Inhibitory Property

Reduction of (6R)-6-amino-6,7-dihydro-2-thienyl-1,4-thiazepin-5(4H)-one derivatives with Mg-MeOH gave the corresponding perhydrothiazepinones.Protection with trityl group at the 6-amino group gave predominantly the 2S,6R isomer which was converted to the
