CuBr-mediated dehydrogenative [4+2] annulation of 1-naphthyl-1,3-indandiones and alkenes. | LitMetric

CuBr-mediated dehydrogenative [4+2] annulation of 1-naphthyl-1,3-indandiones and alkenes.

College of Chemistry and Pharmaceutical Engineering, Nanyang Normal University, Nanyang 473061, China.

Published: August 2024

Intermolecular annulation reactions of 1-naphthyl-1,3-indandiones with alkenes proceed efficiently in the presence of a copper catalyst to generate spirocarbocycle compounds. Various spirocyclic molecules bearing an all-carbon quaternary center could be obtained by this novel method with good yields, excellent regioselectivity, and good functional group tolerance. A radical mechanism is proposed based on the HRMS analysis results of control experiments.
