General Description
4-Acetoxyindole is a chromophore that belongs to the pyrrole family of compounds. It has been shown to react with an ionic liquid under acidic conditions to form a protonated intermediate, which can be deprotonated by a nucleophile. This reaction yields an acetate anion and a fluorescing product. 4-Acetoxyindole also reacts with deuterium gas, yielding an acetate, a deuterium atom, and fluorescing product. The reaction is reversible and the yield of the product depends on the concentration of the reactants. 4-Acetoxyindole has strong carbonyl groups that make it reactive towards other functional groups. These reactions are useful for synthesizing heterocycles such as indoles and isoquinolines.
