• General Description: 2-Carboxybenzaldehyde (also known as 2-formylbenzoic acid) serves as a key reactant in the Ugi four-component condensation (Ugi-4CC) to form stable primary adducts, which can be further transformed into isocoumarins. Its reactivity with phenacylamine dimethyl acetal and isocyanides under controlled conditions allows for the isolation and characterization of intermediates, demonstrating its utility in synthetic routes toward biologically relevant heterocycles. 2-Carboxybenzaldehyde's stability in solid state and tendency to rearrange in solution highlight its role in facilitating efficient and tunable chemical transformations.

Isolation of Ugi four-component condensation primary adducts: A straightforward route to isocoumarins

10.1021/ol9028622

The research presents a study on the isolation of primary adducts from Ugi four-component condensation (Ugi-4CC), which leads to the formation of isocoumarins. The researchers used 2-formylbenzoic acid, phenacylamine dimethyl acetal, and isocyanides as reactants and successfully isolated the primary adducts, which were stable enough for characterization. They also found that using anilines instead of amines yielded stable isocoumarins. The experiments involved stirring the reactants in methanol, followed by filtration to isolate the yellow solid product. The product's structure was confirmed through analytical and spectral data, as well as X-ray diffraction analysis. The study also explored the rearrangement of these primary adducts to form "normal" Ugi-4CC adducts upon treatment with acid and the deprotected Ugi-4CC adducts when exposed to higher concentrations of hydrochloric acid. The researchers highlighted the importance of controlling reaction conditions to ensure good yields and easy workup of the compounds, which were found to be stable in solid state but tended to rearrange in solution. The study provides a straightforward route to isocoumarins, a class of compounds with various biological activities.
