The Versatility of Diazirines: Properties, Synthetic and Modern Applications.

ABSTRACT: Diazirines are 3-membered heterocycles containing two nitrogen atoms connected by a double bond. They are mostly known for their usage in photoaffinity labeling (PAL), due to their stability and their facile photolysis for on-demand carbene generation. Yet diazirines possess a multi-faceted reactivity that also holds great potential for organic synthesis. This is illustrated in the present review, which is meant to be a beginner's guide for new diazirine users. After briefly summarizing the main synthetic approaches to these derivatives (with a focus on recent improvements), we emphasize some of their most critical features and properties before describing the various modes of activation toward carbene generation, some of which were only uncovered in the past decade. We then review the man
