该中间体在本合成路线中的序号:(XLVIII)In a variation of the preceding methods, the chiral glycidic amide (XLVII) was used as the synthetic precursor. Amide (XLVII) was either prepared by treatment of the chiral glycidic ester (VI) with ammonia, or by enzymatic resolution of (XII), followed by amidation. Iron-catalyzed addition of 2-aminothiophenol (VII) to the glycidamide (XLVII) in refluxing chlorobenzene yielded the desired threo adduct (XLVIII) as the major isomer. Cyclization of amino amide (XLVIII) under acidic conditions furnished thiazepinone (VIII)
