  Compounds of Formula (I): where X is S and the variables have the meaning defined in the specification are specific or selective to alpha2B and/or alpha2C adrenergic receptors in preference over alpha2A adrenergic receptors, and as such have no or only minimal cardivascular and/or sedatory activity. These compounds of Formula (I) are useful as medicaments in mammals, including humans, for treatment of diseases and or alleviations of conditions which are responsive to treatment by agonists of alpha2B adrenergic receptors. Compounds of Formula (I) where X is O also have the advantageous property that they have no or only minimal cardivascular and/or sedatory activity and are useful for treating pain and other conditions with no or only minimal cardivascular and/or sedatory activity.

  式(I)的化合物：其中X为S，变量的含义如规范中定义的那样，对alpha2B和/或alpha2C肾上腺素受体具有特异性或选择性，优先于alpha2A肾上腺素受体，并且因此具有无或仅有极小的心血管和/或镇静活性。这些式(I)的化合物在哺乳动物，包括人类中，作为药物用于治疗对alpha2B肾上腺素受体激动剂治疗有响应的疾病和/或缓解症状是有用的。式(I)的化合物，其中X为O，还具有有利的特性，即它们具有无或仅有极小的心血管和/或镇静活性，并且适用于治疗无或仅有极小的心血管和/或镇静活性的疼痛和其他症状。

  The compound of the formula wherein the * indicates an asymmetric carbon, is specific to alpha 2B adrenergic receptors in preference over alpha 2A and alpha 2C adrenergic receptors, and as such has no or only minimal cardivascular and/or sedatory activity. The compound is useful as medicament in mammals, including humans, for treatment of diseases and or alleviations of conditions which are responsive to treatment by agonists of alpha 2B adrenergic receptors.

  该化学式的化合物，其中*表示一个不对称碳原子，对α2B肾上腺素受体具有特异性，优先于α2A和α2C肾上腺素受体，因此几乎没有或仅有极小的心血管和/或镇静活性。该化合物可用作哺乳动物，包括人类，治疗对α2B肾上腺素受体激动剂治疗敏感的疾病和/或缓解症状的药物。
• Acceleration Effect of an Allylic Hydroxy Group on Ring-Closing Enyne Metathesis of Terminal Alkynes: Scope, Application, and Mechanistic Insights

  日期：——

  acceleration effect of an allylic hydroxy group on ring-closing enyne metathesis has been found. Ring-closing enyne metathesis of terminal alkynes possessing an allylic hydroxy group proceeded smoothly without the ethylene atmosphere generally necessary to promote the reaction. The synthesis of (+)-isofagomine with the aid of this efficient reaction has been demonstrated. Mechanistic studies of the acceleration

  已经发现烯丙基羟基对闭环烯炔复分解的有趣的加速作用。具有烯丙基羟基的末端炔烃的闭环烯炔复分解反应顺利进行，而通常没有促进反应所需的乙烯气氛。已经证明了借助该有效反应的（+）-异黄花碱的合成。还进行了加速作用的机理研究。NMR研究的结果表明反应是通过“烯-然后-炔”途径进行的。动力学研究表明，由于存在烯丙基羟基，导致速率确定步骤的切换。这些结果表明，烯丙基羟基加速了Ru-卡宾物质的再进入步骤。
