  N-Acetic acid derivatives (I) of 2-substituted 1, 4-benzoxazines and benzothiazines were designed and synthesized for evaluation as new aldose reductase inhibitors. In general, 3-thioxo derivatives were more potent inhibitors of aldose reductase from human placenta in vitro than the corresponding 3-oxo derivatives. While many compounds (I) were not very effective in inhibiting sorbitol accumulation in the rat sciatic nerve in vivo, the 3-thioxo compounds bearing an isopropyl group at the 2-position showed highly potent activity in the in vivo assay. Compound 46 (AD-5467) was selected from this series as a candidate for further development.

  N-乙酸衍生物（I）的2-取代基1,4-苯并恶嗪和苯并噻嗪被设计合成，以评估其作为新型醛糖还原酶抑制剂的潜力。一般而言，3-硫代羰基衍生物在体外对人胎盘醛糖还原酶的抑制活性比相应的3-氧代衍生物更强。虽然许多化合物（I）在体内对大鼠坐骨神经山梨醇积累的抑制作用并不十分有效，但在体内试验中，2-位带有异丙基的3-硫代羰基化合物显示出极强的活性。从这一系列中选出化合物46（AD-5467）作为进一步开发的候选药物。

  (4-phenyl-1-piperazinyl)alkyl moieties at the 2-position were synthesized and tested for calcium antagonistic and calmodulin antagonistic activities. Antihypertensive effects in spontaneously hypertensive rats were also evaluated. In general, these compounds were rather weak calcium channel blockers, although, in contrast, many of them had moderate to potent calmodulin antagonistic activity, and 2-[3-

  4. Identical products (4) were obtained by refluxing 1 or 6 in ethanol in the presence of triethylamine. The structure of 4 was confirmed by their alternate synthesis starting with diethyl chloromalonate in ethanol in the presence of triethylamine which yielded the intermediate 1,4-benzothiazine derivatives 8. The subsequent coupling of 8 with diazotized anilines in ethanol in the presence of potassium

  在三乙胺的存在下，在乙醇中使芳基肼基氯乙酸乙酯（1）与2-氨基硫代苯酚（2）反应，得到相应的硫代肼基甲酸乙酯（3）。类似地，芳基肼基氯乙酸甲酯（6）得到相应的硫代肼基甲酸甲酯（7）。用乙醇中的氯化氢处理3和7分别得到1,4-苯并噻嗪衍生物4。在三乙胺存在下，在乙醇中回流1或6，得到相同的产物（4）。4的结构通过在氯乙二酸二乙酯在乙醇中，在三乙胺的存在下进行交替合成，证实了它们的合成，从而得到中间体1,4-苯并噻嗪衍生物8。随后在氢氧化钾存在下，将8与重氮化苯胺在乙醇中偶联，得到4。

  A new approach for the synthesis of 2-hetaryl derivatives of 3-oxo-3,4-dihydro-2H-1,4-benzothiazines is described. 2-Chloro derivatives of 2a,b were reacted with electron-rich heterocycles 3-14 under basic catalysis (with a slight excess of Et3N) to provide the substitution products 16-36. In the reaction of 2b with 14 and 15, an intermolecular cyclization took place between the amino and ethoxycarbonyl groups, resulting in spiro compounds 35 and 36, respectively.
