In the course of investigations aimed at designing fluorescent metal-free click ligations for application in bioconjugation and drug design, we turned our attention to the use of azomethine-ylides as dipoles for [3+2] cycloadditions. In this regard, pyridinium-ylides, generated in situ from suitable pyridinium salts, are of great interest due to their good reactivity with activated alkynes, such as propiolic acid derivatives or conjugated alkynes. In addition, the corresponding fluorescent indolizines are formed in a regioselective manner and any catalyst is required. From the outset, we defined a specific set of requirements for these ligations, most notably that they be biocompatible (i.e. physiological conditions, pH 7, room temperature)...
