Barton esters were prepared starting from different carboxylic acids loaded on a Wang resin. Light induced fragmentation occurred giving a radical that reacted with CBrCl3 to give the corresponding bromides, whereas conjugate addition to electron-poor alkenes proved to be less synthetically useful. The bromides so formed were further functionalised on the resin with different nucleophiles.

molecules with novel skeletons, but also to identify the enzymes that catalyze diverse chemical reactions. Exploring the substrate promiscuity and catalytic mechanism of those biosynthetic enzymes facilitates the development of potential biocatalysts. SfaB is an acyladenylate‐forming enzyme that adenylates a unique building block, 3‐isocyanobutanoic acid, in the biosynthetic pathway of the diisonitrile
