A Modular Approach to Functionalised Dyes

Abstract

A modular approach to the synthesis of sensors is described. In this approach a central dye scaffold, prepared from the S_NAr reaction between a halo-substituted azo-dye and a disubstituted phenol, was decorated with a representative carbohydrate or macrocycle using Sharpless click chemistry. Regiochemical issues in the click reaction are also addressed.

Key words

azo-dye - recognition - click - macromolecule - crown ethers - cycloaddition - regiocontrol - aziridine - scaffold - sensors

The reaction mixture was heated for 48 h at 130 °C. The reaction mixture was allowed to cool and then added EtOAc in it. The organic layer was separated, and the aqueous layer was re-extracted with EtOAc. The combined organic layer was dried over MgSO₄ and reduced in vacuo. The crude product was purified by column chromatography (hexane–EtOAc, 1:4) affording the title compound as a colourless oil, yield 58% (see SI for spectroscopic data).
