3-Hydroxyoctahydro-4H-inden-4-ones and 7-hydroxyoctahydro-1H-inden-1-ones (1, 2 and 3, 4, respectively), as well as the homologous 3-hydroxyoctahydro-4(1H)-azulenones (5, 6) and 8-hydroxyoctahydro-1(2H)-azulenones (7, 8), were prepared diastereoselectively either from the precursor α,β-enones 9, 10, 11, and 12 or by an isoxazoline method. Unmasking of the isoxazolines 13i, 14i, and 14j with O3 proved
