• An Ethynyl-Substituted 1,5,7-Trimethyl-3-azabicyclo[3.3.1]nonan-2-one as a Versatile Precursor for Chiral Templates and Chiral Photocatalysts
  作者：Thorsten Bach、Felix Voss

  DOI：10.1055/s-0029-1219920

  日期：2010.6

  The title compound was synthesized and separated into its enantiomers. The enantiomerically pure alkyne was ligated to several aryl azides and aryl halides. The resulting 7-substituted 1,5,7-trimethyl-3-azabicyclo[3.3.1]nonan-2-ones were used either as chiral templates in the intramolecular [2+2] photocycloaddition of 4-allyloxyquinolone (up to 72% ee) or as a chiral photocatalyst for the intramolecular [2+2] photocycloaddition of 4-(3-butenyl­oxy)quinolone (up to 79% ee with 10 mol% catalyst).

  公开（公告）日：2002-11-14

  The present invention discloses novel aromatic azide derivatives and their bioconjugates for phototherapy of tumors and other lesions. The organic azides of the present invention are designed to absorb low-energy ultraviolet, visible, or near-infrared (NIR) region of the electromagnetic spectrum. The phototherapeutic effect is caused by direct interaction of nitrene, the reactive intermediate produced upon photoexcitation of the aromatic azide, with the tissue of interest. The compounds of the present invention are administered to a patient, allowed to accumulate at the site of the tumor or other lesion, and are exposed to light in order to perform a phototherapeutic procedure.

  本发明公开了用于肿瘤和其他病变光疗的新型芳香族叠氮化物衍生物及其生物共轭物。本发明的有机叠氮化物可吸收电磁波谱中的低能量紫外线、可见光或近红外（NIR）区域。光疗效果是由芳香族叠氮化物光激发时产生的反应性中间体--腈与相关组织直接相互作用而产生的。给病人服用本发明的化合物，让其在肿瘤或其他病变部位积聚，并将其暴露在光下，以进行光治疗程序。
