first synthesis has been achieved of the racemates of valienamine and its related, branched-chain unsaturated aminocyclitols. Two synthetic routes for valienamine were developed, one of which is stereoselective and highly efficient. The key transformation is a stereospecific SN2′ attack (apofacial) by an azide ion on the allyl chloride, prepared by regioselective epoxidation of the conjugated diene
