Reaction of 2-aminoethanethiol (3) with trans-3-(p-methoxyplienyl)glycidate (4) gave the rac.-cis-1,4-thiazepinone 5 and a by-product 6. The structure of 5 was proven by X-ray crystallography. The X-ray data revealed that this compound adopts the chair conformation in the solid state and the heterocyclic ring is sevenmembered. The structure of the by-product 6 was elucidated on the basis of spectral
