Facile and Practical Synthesis of Substituted Piperidine-2,6-Diones Under Transition-Metal Free Condition.

ABSTRACT: Substituted piperidine-2,6-diones are privileged scaffolds in numerous bioactive molecules and their facile and practical preparation still remains unsolved. In this paper, a facile and practical approach for the construction of α-substituted and α,α-/α,β-disubstituted piperidine-2,6-diones from abundant methyl acetates and acrylamides under transition-metal free condition was disclosed. It features mild reaction condition, operational simplicity, and excellent functional group tolerance, delivering a wide range of piperidine-2,6-diones in moderate to good yield. Furthermore, the application potential was further demonstrated by reaction scale-up (5 kilo-gram scale) and bio-active molecule synthesis (Aminoglutethimide and Niraparib). Additional control experiments revealed that the radical
