WebSynthesis of conjugatable BODIPY fluorophores. Access to water-soluble carbohydrate-BODIPY hybrids. At the beginning of our studies, only a few examples on the preparation of carbohydrate-BODIPY hybrids existed in the literature, [], and a key factor to the success on the investigations compiled in this manuscript was the launching of a collaboration with … WebThe following step is iodination to add iodine atoms to the BODIPY core; this modification is described to promote singlet oxygen generation in the final compound. The step after iodination adds two equivalents of p -tolualdehyde to the scaffold through Knoevenagel condensation to extend the conjugation of the final compound 3 with a yield of 49%.
