The synthesis of 2-azi-camphane has been achieved despite the fact that the spirocyclic carbon center is stericallycongested. Although the yield is somewhat low, the highly pure diazirine can be used as a precursor for the burgeoning class of stericallycongested carbenes.

The optimized synthesis of 2-azicamphane (5), a sterically hindered 3,3-dialkyldiazirine, has finally made this interesting chiral diazirine available in useful quantities. The specific reaction conditions are discussed with regard to further general applications for future syntheses of diazirines that, until now, could not be prepared.
