Abstract New preparative routes to the isomeric damascones (2, 4 and 9) and β- damascenone (1) starting from the readily accessible ionone isoxazoles [11] are described. γ-Damascone (9) was prepared from 10 following the Büchi-Vederas transformation [11], while α-and β-damascone (4 and 2) were obtained as the end products of the reaction sequence: β-aminodamascones [11][RIGHTWARDS ARROW] β-ketodihydrodamascones ...
