Cycloaddition of substituted spiroepoxycyclohexa-2,4-dienones: synthesis and X-ray crystal structure of the adducts

[摘要] The syntheses of the tricyclic ketoepoxides 1 and 2 from the readily available aromatic precursors 5 and 6 via cycloaddition of the spiroepoxycyclohexa-2,4-dienones 3 and 4 are described. The crystal structures of 1 and 2 were determined. (C) 2002 Elsevier Sciencc Ltd. All rights reserved.
