product by an aromatic ring. This design element is general and the synthesis is straightforward, providing ready access to libraries of polyfunctional fluorophores with long Stokes shifts based on the epicocconone core. Our structural modifications resulted in analogues with increased photostability and quantum yields compared with the natural product. Staining proteomic gels with these new analogues

The IBX twist does it: Towards the synthesis of a recently isolated dihydropyranic azaphilone core framework, a 2‐iodoxybenzoic acid (IBX)‐mediatedoxidative dearomatization was performed on a bicyclic substrate with excellent diastereoselectivity. Trifluoroacetic acid (TFA) esters were obtained as single diastereomers and water was shown to increase both the speed and diastereoselectivity of the reaction
