  摘要：

  在强酸介质中苄基磺酰胺与醛的环化是合成3,4-二氢-1 H -2,3-苯并噻嗪2,2-二氧化物III的合成途径。在不足的酸强度或反应时间的情况下，获得了动力学产物IV和VI。后者的化合物可以在更强的条件下转化为热力学产物III。反应通过亚胺VII或亚胺VIII化合物作为常见中间体进行。

  The synthesis of 3,4-dihydro-1H-2,3-benzothiazine 2,2-dioxides and 1,2,4,5-tetrahydro-3,2-benzothiazepine 3,3-dioxides is studied using sulfated zirconia as catalyst. The sulfated zirconia calcined at 550 A degrees C achieved a high selectivity which is attributed to the formation of a tetragonal phase. In addition, the catalyst can be reused up to three times without loss of its catalytic activity.
