In this study, a significantly improved method for the synthesis of modular meso-BODIPY (boron dipyrromethene) derivatives possessing a free carboxylic acid group (which was subsequently coupled to peptides), is disclosed. This method provides a vast

We report a mild and efficient Cu(OAc)2-catalysed protocol for the oxidative C–N cross-coupling of terminal alkynes and N-deprotected sulfonimidamides. The reaction leads to hitherto unknown N-alkynylated sulfonimidamides. Furthermore, we found tha

N′-Vinyl sulfonimidamides have been synthesized through a Pd-catalyzed C–N cross coupling between the N′-(imine nitrogen) of N′-deprotected sulfonimidamides and vinyl bromides. The hitherto unreported products were obtained in moderate to exc
