  FormylBODIPYs: Privileged Building Blocks for Multicomponent Reactions. The Case of the Passerini Reaction

  摘要：

  Eleven formyl-containing BODIPY dyes were prepared by means of either the Liebeskind-Srogl cross-coupling reaction or the Vilsmeier reaction. These dyes were used as components in the Passerini reaction to give highly substituted BODIPY dyes. A joined spectroscopic and theoretical characterization of the synthesized compounds was conducted to unravel the impact of the structural rigidity/flexibility on the photophysical signatures. These dyes were tested as fluorescent trackers for phagocytosis. Additionally, they proved to be useful to stain different blood cells with an intense and stable signal at a very low exposure time.

  α-/β-甲酰化硼二吡喃 (BODIPY) 染料：区域选择性合成和光物理特性

  摘要：

  基于 Vilsmeier-Haack 反应，已对吡咯未取代的二吡咯甲烷 1 和硼-二吡喃 (BODIPY) 染料 4 进行甲酰化。对于吡咯未取代的二吡咯甲烷 1 和 BODIPY 染料 4，它具有高度的区域选择性和互补性，分别仅出现在 α-和 β-位。这种区域选择性甲酰化可以合成各种 α- 和 β-取代的 BODIPY 染料。甲酰基的安装会影响 BODIPY 发色团的电子特性，导致 α- 和 β-甲酰化 BODIPY 3 和 5 的吸收和发射最大值分别发生红移和蓝移。

  pyrrole-unsubstituted dipyrromethanes 1 and boron–dipyrrin (BODIPY) dyes 4 based on a Vilsmeier–Haack reaction. It is highly regioselective and complementary and occurs exclusively at the α- and β-position, respectively, for pyrrole-unsubstituted dipyrromethanes 1 and BODIPY dyes 4. This regioselective formylation enables the syntheses of a variety of α- and β-substituted BODIPY dyes. The installation of formyl groups
