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
2-氨基乙硫醇(3)与反式-3-(对甲氧基吡啶基)缩水甘油酸酯(4)的反应给出了rac.-顺-1,4-噻嗪酮5和副产物6。X射线晶体学证明5的结构。X射线数据表明该化合物在固态下采用椅子构象,杂环为七元。根据光谱数据阐明了副产物6的结构。化合物9和10作为钙通道阻滞剂是无活性的。
