Abstract

1,3-Dicarbonyl compounds react with methylenecyclopropanes by oxidation with CAN to give spirocyclopropyl dihydrofuran derivatives in good yields.

This is not surprising, as we have reported that MeOH is the ideal solvent for CAN-mediated addition of active methylene compounds to alkenes (see ref. 7).
