Metal-Free Synthesis of Dibenzoxazepinones via a One-Pot SNAr and Smiles Rearrangement Process: Orthogonality with Copper-Catalyzed Cyclizations
摘要:
Reported is the transition-metal-free synthesis of substituted dibenzoxazepinones using a convergent domino SNAr-Smiles rearrangement-SNAr process. Substrate-scope investigations demonstrated the critical importance of ring electronic effects on the efficiency of the process. In addition, the orthogonality of this approach with transition-metal-catalyzed procedures was established.
