    efficient approach for the synthesis of fluorescent 2,3-naphthalimide derivatives has been developed from readily available starting materials via an intramolecular didehydro-Diels–Alder reaction, which proceeded well under room temperature, exhibiting a wide substrate scope and good functional group tolerance. The practicability of this methodology has been verified by one-step synthesis of the environmentally
    已经开发了一种实用,有效的方法来合成荧光2,3-萘二甲酰亚胺衍生物,该方法是通过分子内的双氢Dielshydro-Diels-Alder反应从易于获得的起始原料中合成的,该反应在室温下进行良好,具有广泛的底物范围和良好的官能团宽容。该方法的实用性已通过克级的环境敏感荧光团6-DMN的一步合成得到了验证,该合成具有更短的时间,更少的步骤和更少的废物处理,并且没有利用有毒的过渡金属。目前的实验和计算研究支持丙硫酰亚胺部分在转化中的关键作用。

    Compounds of Formula 1 1 where X is S and the variables have the meaning defined in the specification are specific or selective to alpha 2B and/or alpha 2C adrenergic receptors in preference over alpha 2A adrenergic receptors, and as such have no or only minimal cardivascular and/or sedatory activity. These compounds of Formula 1 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 alpha 2B adrenergic receptors. Compounds of Formula 1 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.
