New and efficient syntheses of (+/-)-ambrox (1a), (+/-)-ambra oxide (2a) and their stereoisomers (1b, 2b ca. c), amber-like odorous compounds, are described.Starting from dihydro β- and α-ionone (5,12), these substances were obtained in only a few steps via stereoselective acid-catalized cyclization of monocyclodienoic acid (7a ca. b, 11a ca. b, 15a).
