Synthesis of functionalized fulvenes: [3 + 2] annulation of ethyl α-chlorocyclopropaneformates with 1,3-dicarbonyl compounds

A base-promoted [3 + 2] annulation reaction of ethyl α-chlorocyclopropaneformates with 1,3-dicarbonyl compounds is described. This method provides an efficient and straightforward route to acidic multi-substituted fulvenes with distinctive properties.
