Abstract

Three cyclooctitol derivatives, in the form of a tetraacetate, (1S,2R,3S,4S)-2,3,4-triacetoxycyclooctan-1-ylmethyl acetate, C17H26O8, 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-diacetoxy-2,2-dimethylcyclooctano[d][1,3]dioxan-4-ylmethyl acetate, both C18H28O8, 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.
