title: 2,6-Diazaspiro[3.3]heptanes: synthesis and application in Pd-catalyzed aryl amination reactions.
abstract: A concise and scalable synthesis of a 2,6-diazaspiro[3.3]heptane building block is reported. The usefulness of this structural surrogate of piperazine is shown in arene amination reactions yielding a variety of N-Boc- N'-aryl-2,6-diazaspiro[3.3]heptanes.
