• A New Photolabile Protecting Group for Release of Carboxylic Acids by Visible-Light-Induced Direct and Mediated Electron Transfer
  作者：J. Brian Borak、Daniel E. Falvey

  DOI：10.1021/jo900182x

  日期：2009.5.15

  A new aqueous-compatible photoinduced electron transfer based photolabile protecting group has been developed for the release of carboxylic acids. The reduction potential of this group is more positive than previous systems, thereby allowing the use of sensitizers with modest oxidation potentials. Release of several carboxylic acids has been demonstrated using tris(bipyridyl)ruthenium(II) as both a

  已经开发了一种新的与水相容的光诱导的基于电子转移的光不稳定保护基团，用于释放羧酸。该组的还原电势比以前的系统更强，因此可以使用具有适度氧化电势的敏化剂。使用三（联吡啶基）钌（II）作为直接敏化剂和良好施主与保护基团之间电子转移的介体已证明了几种羧酸的释放。
