New aromatic annulation reaction via a C14 enaminone synthon: Synthesis of 'terpenoid-like chalcones'

Valla, Alain,Valla, Benoist,Cartier, Dominique,Le Guillou, Régis,Labia, Roger,Potier, Pierre

, p. 6671 - 6674 (2005)

Diverse functionalized synthons from a new enaminone are reported. These synthons were easily obtained in a one pot process starting from a compound derived from β-ionone. A new annulation reaction of this C-14 compound with several anions led to new 'terpenoid-like' chalcones.
