  异构纯四甲基罗丹明电压报告器

  摘要：

  我们展示了基于异构纯四甲基罗丹明的新型荧光电压指示剂系列的设计、合成和应用。这些新型罗丹明电压报告器 (RhoVR) 使用光诱导电子转移 (PeT) 作为电压传感的触发器，在可见光谱的绿色到橙色区域显示激发和发射曲线，表现出对膜电位变化的高灵敏度（高达 47 % ΔF/F 每 100 mV），并采用源自肌氨酸的叔酰胺，这有助于膜定位，同时简化了电压传感器的合成路线。 RhoVR 染料中最灵敏的 RhoVR 1 在罗丹明芳环的 5' 位具有甲氧基取代的二乙基苯胺供体和亚苯基亚乙烯基分子线，在基于 PeT 的红移电压传感器中表现出迄今为止最高的电压灵敏度，并且与基于绿色荧光蛋白的指示剂同时成像兼容。分子线电压指示剂中基于肌氨酸的叔酰胺可防止染料内化，并且 5' 取代的电压指示剂表现出改善的电压灵敏度，这一发现应该广泛适用于其他类型的基于 PeT 的电压敏感荧光团。

• Access to β-Keto Esters by Palladium-Catalyzed Carbonylative Coupling of Aryl Halides with Monoester Potassium Malonates
  作者：Signe Korsager、Dennis U. Nielsen、Rolf H. Taaning、Troels Skrydstrup

  DOI：10.1002/anie.201304072

  日期：2013.9.9

  New tricks for an old dog: The Pd‐catalyzed carbonylative α‐arylation of monoethyl potassium malonates with aryl bromides and reactive aryl chlorides provides a simple and direct route to aryl β‐ketoesters. Because only stoichiometric amounts of carbon monoxide are employed, the method is ideal for the introduction of carbon isotopes into more complex structures.

  老狗的新招数：丙二酸单乙酯钾的Pd催化羰基α-芳基化与芳基溴化物和反应性芳基氯化物的合成提供了一条简单而直接的途径制备芳基β-酮酸酯。由于仅使用化学计量的一氧化碳，因此该方法非常适合将碳同位素引入更复杂的结构中。
