representatives of this novel class of triazide compounds: Despite their high nitrogen content, the geminaltriazides are easy to handle, even when preparative‐scale syntheses are performed. (Caution: These procedures still require protective measures!) The triazides are now broadly available for further studies regarding their properties and reactivity. Furthermore, we show how the method can be used to

The organocatalyzed decarboxylative addition of substituted malonic acid half oxyesters (SMAHOs) to dialkyl azodicarboxylates led to the formation of α-aminoester derivatives. The reaction can be performed under mild reaction conditions using 1,4-diazabicyclo[2.2.2]octane (DABCO) as a catalyst and displayed a rather important scope.
