This paper evaluates a series of photolabile protecting groups with built-in fluorescence reporting. They rely on readily available o-acetoxyphenyl methyloxazolones as activated precursors. Alcohol substrates are easily caged. The resulting photoactivable esters exhibit large one- and two-photon uncaging cross sections. The alcohol substrates are quantitatively released in a 1:1 molar ratio with a
本文利用内置的荧光报告评估了一系列对光不稳定的保护基。他们依靠现成的邻乙酰氧基苯基甲基恶唑酮作为活化的前体。酒精基质很容易笼罩。所得的可光活化的酯表现出大的单光子和双光子解开截面。醇底物与强荧光香豆素副产物以1:1摩尔比定量释放,该香豆素副产物用作定量底物递送的报告分子。
