Synthesis of 1,2-Diketones from beta-Keto Nitriles via a Protection-Oxidative-Decyanation-Deprotection Protocol

[摘要]：A variety of 1,2-diketones were prepared from beta-keto nitriles via a three-step protocol including the protection of the ketones with methoxyamine, oxidative decyanation, and microwave-assisted deprotection in the final step. This approach provides a novel and efficient access to a wide scope of symmetric and unsymmetric 1,2-diketones using molecular oxygen as the oxidant in the decyanation process.
