  摘要：

  合成了具有硝基和醚基取代基的3-苯基-3-三氟甲基-二氟啉衍生物，作为光标记产物的卡宾前驱体用于色谱检测。在甲醇或环己烷中光解二氟啉分别生成了分子间的O-H或C-H插入产物。光产物的光谱特性使得在大多数生物大分子的吸收可以忽略的光谱区域内进行光标记产物的检测成为可能。还制备了二氟啉的碳-14同位素类似物，用于微量标记产物的检测。这些硝基取代的芳基二氟啉应适用于广泛的光亲和标记研究，从示踪实验到通过HPLC配合光谱光度检测进行标记产物的制备分离。

  A Novel Family of Aromatic Diazirines for Photoaffinity Labeling

  摘要：

  A series Of simple methods for modifying diazirines bearing an aromatic ring has been accomplished. This first versatile approach involving direct substitution on the aromatic ring of diazirines has been achieved by means of the aromatic thallation of (alkoxyphenyl)diazirines. Introduction of the thallium moiety was successfully followed by nitration, iodination, or palladium-catalyzed carbonylation to give a family of substituted aryldiazirines useful for photolabeling. For instance, diazirines labeled with a nitro group can be detected by spectrophotometric methods, and those labeled with an iodo group can be useful in tracer experiments. The (methoxyphenyl)diazirines were also found to be stable under certain demethylation conditions, thus providing a potential source of diazirines with modifiable phenol hydroxyl groups. By means of this approach, a spacer arm to link diazirines with ligands was readily introduced. Radioactive diazirines labeled with carbon-14 or tritium were also prepared using this method. All the new diazirines were derived from a pair of simple (methoxyphenyl)diazirines. The ease of derivatization of the (alkoxyphenyl)diazirines described here may offer a practical approach to simplify the time-consuming methods currently used for diazirine synthesis.
