were prepared from β-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. β-keto nitriles - oxygen - oxidative
通过三步方案从β-酮腈制备了各种1,2-二酮,包括在最后一步用甲氧基胺保护酮,氧化脱氰和微波辅助脱保护。这种方法在脱氰过程中使用分子氧作为氧化剂,提供了一种新颖而有效的途径,可以广泛地使用对称和不对称的1,2-二酮。 β-酮腈-氧气-氧化脱氰-微波-1,2-二酮
