  Vitamin E-inspired multi-scale imaging agent

  摘要：

  The production and use of multi-modal imaging agents is on the rise. The vast majority of these imaging agents are limited to a single length scale for the agent (e.g. tissues only), which is typically at the organ or tissue scale. This work explores the synthesis of such an imaging agent and discusses the applications of our vitamin E-inspired multi-modal and multi-length scale imaging agents TB-Toc ((S,E)-5,5-difluoro-7-(2-(5-((6-hydroxy-2,5,7,8-tetramethylchroman-2-yl) methyl) thiophen-2-yl) vinyl)-9-methyl-5H-dipyrrolo-[1,2-c:2',1'-f] [1,3,2] diazaborinin-4-ium-5-uide). We investigate the toxicity of TB-Toc along with the starting materials and lipid based delivery vehicle in mouse myoblasts and fibroblasts. Further we investigate the uptake of TB-Toc delivered to cultured cells in both solvent and liposomes. TB-Toc has low toxicity, and no change in cell viability was observed up to concentrations of 10 mM. TB-Toc shows time-dependent cellular uptake that is complete in about 30 min. This work is the first step in demonstrating our vitamin E derivatives are viable multi-modal and length scale diagnostic tools.

  nondirected amidation reaction of aromatic C–H bond was developed under iron(II) catalysis, using sulfonyl azides as the nitrogen source. The reaction displayed a broad substrate scope and good regioselectivities in the aspects of aromatic ring vs alkyl chain and different aromatic position of (alkyl)arenes. This method provided a new protocol for the synthesis of some aromatic amines, which were hard

  在铁（II）催化下，使用磺酰基叠氮化物作为氮源，开发了芳香族CH键的非定向酰胺化反应。该反应在芳族环对烷基链和（烷基）芳烃的不同芳族位置方面显示出较宽的底物范围和良好的区域选择性。该方法为合成某些芳族胺提供了新的方案，在先前的报告中很难实现。
