Abstract: A copper-catalyzed annulation of O-acyl oximes with cyclic 1,3-diones has been developed for the concise synthesis of 7,8-dihydroindolizin-5(6H)-ones and cyclohexanone-fused furans through the substituent-controlled selective radical coupling process. 2-Alkyl cyclic 1,3-diones undergo C-C radical coupling,… read more here.

Abstract: An iron-catalyzed [3 + 2] annulation of O-acyl oximes with 2-hydroxy-1-naphthoates has been developed. This strategy features the simultaneous activation of both substrates to form two radical intermediates. Subsequent selective C-N radical coupling followed by… read more here.
