A complementary set of stereochemically controlled approaches to the preparation of twelve diastereomers of the bistetrahydrofurans 11 is described. The key transformation involves a series of nucleophilic displacement reactions within triepoxides 19-the “end-to-end” triepoxide cascade reaction—which leads, presumably via 22 and 23, after acetylation to bistetrahydrofuran tetraacetates 24. The “inside-out”
