Three cyclooctitol derivatives, in the form of a tetraacetate, $(1S^*,2R^*,3S^*,4S^*)$-2,3,4-triacetoxycyclooctan-1- ylmethyl acetate, $C_{17}H_{26}O_8$, and two regioisomeric acetonide triacetates, $(3aS^*,4R^*,8S^*,9S^*,9aS^*)$ -8,9-diacetoxy-2, 2-dimethylcyclooctano-[d][1,3]dioxan-4-ymethyl acetate and $(3aS,4R,7S,9R,9aS)$-7,9-diacet-oxy-2,2-dimethyl-cyclo-octano[d][1,3] dioxan-4-ylmethyl acetate, both $C_{18}H_{28}O_8$, have been studied. The conformation of the cyclooctane ring in the three compounds is quite close to the boat-chair form of the parent hydrocarbon. Packing is effected through weak C - H... O and van der Waals contacts.
