Orthogonally Protected Oxadiazole-Based Building Blocks: Synthesis and Characterization

We present a straightforward route for the preparation of orthogonally protected oxadiazole-based building blocks in high yields. Their structures contain a Boc-protected amine and an ester group, thus rendering the compounds amenable to functionalization or integration into larger structures. Thus, we provided access to interesting and innovative building blocks/decorated scaffolds for drug discovery.
