Facile and chemoselective rhodium-catalysed intramolecular hydroacylation of α,α-disubstituted 4-alkylidenecyclopropanals

Author affiliations

Abstract

Mild intramolecular hydroacylation of α,α-disubstituted 4-alkylidenecyclopropanals has been developed, avoiding decarbonylation and affording cycloheptenones in good yields. The reaction is chemoselective in favour of the alkylidenecyclopropane moiety when potential alkene or alkyne acceptors are tethered to the substrate.
