Abstract
7-Acetoxyheptanal, 7-(2-tetrahydropyranyloxy)heptanal and 8-(2-tetrahydropyranyloxy)octanal were prepared, in good yields, from 7-nitroheptanol and 8-nitrooctanol, via conversion of alcohol, to the corresponding acetate or tetrahydropyranyl derivative, then transformation of the nitro group into aldehyde, by the Nef reaction.
