The complete hydrogenolysis of compounds containing the geminaldiazido functionality is described. Using hydrogen over palladium on charcoal, the diazides are reduced, and primary amines are obtained. For example, aminomalonates and glycines are generated in a straightforward manner. A protocol that provides direct access to acetylated amines derived from 2-amino-1,3-diketones in good to excellent

Diazidated malonamides derived from amines and diazidated diethyl malonate react with lithiated alcohols through nucleophilic substitution reactions where azide acts as an unconventional leaving group. This deazidoalkoxylation leads to the formal construction of N,O-acetals, and the remaining azide functionality is a useful entry point for further functionalizations through, for example, standard cycloaddition
