  日期：——

  A practical and efficient method is established for the direct oxidative lactonization of the C(sp3)–H bonds relying on visible-light-induced photoredox catalysis. This protocol expediently allows the delivery of diverse phthalides using oxygen as the sole terminal oxidant under metal-free conditions at room temperature. Notably, the choice of an appropriate hydrogen atom transfer (HAT) cocatalyst

  建立了一种实用且有效的方法，用于依赖可见光诱导的光氧化还原催化的 C(sp 3 )-H 键的直接氧化内酯化。该协议方便地允许在室温下在无金属条件下使用氧气作为唯一的终端氧化剂输送各种苯酞。值得注意的是，选择合适的氢原子转移 (HAT) 助催化剂对这一过程的成功至关重要。

  Labels are disclosed capable of forming a covalent or non-covalent bond with a target molecule, particularly a biological molecule. The structure of these labels may consist of a dye covalently bound by one or more carbons on its chemical structure to one or more [FUNC] group(s), and optionally one or more [SOL] group(s). The structure of these labels allow selection of dyes from a wide variety of different excitation and emission wavelengths and allow easy functionalization of the dye without appreciably altering its spectral characteristics or its solubility characteristics.

  标签可以与目标分子形成共价或非共价键，特别是生物分子。这些标签的结构可能由染料共价结合到其化学结构上的一个或多个碳上，以及一个或多个[FUNC]基团，和可选地一个或多个[SOL]基团。这些标签的结构允许从各种不同的激发和发射波长中选择染料，并且允许轻松地对染料进行功能化，而不会明显改变其光谱特性或溶解特性。
