Efficient synthesis of aziridinecyclooctanediol and 3-aminocyclooctanetriol

Abstract
Cyclooctene endoperoxide was used as the key compound for the synthesis of aziridinecyclooctanediol and 3-aminocyclooctanetriol. Reduction of the cyclooctene endoperoxide, prepared by photooxygenation of cis,cis-1,3-cyclooctadiene, with zinc gave a cyclooctenediol and then benzylation of the hydroxy group yielded dibenzylated cyclooctene. Oxidation of the latter compound by OsO4/NMO followed by mesylation of the hydroxy group provided bis(benzyloxy)cyclooctane-1,2-diyl dimethanesulfonate. Reaction of the bis(benzyloxy)cyclooctane-1,2-diyl dimethanesulfonate with NaN3 gave 2-azido-3,8-bis(benzyloxy)cyclooctyl methanesulfonate. Reduction of the azide group and debenzylation to give an amine provided the new 3-aminocyclooctanetriol. Treatment of the 2-azido-3,8-bis(benzyloxy)cyclooctyl methanesulfonate with Zn/NH4Cl and debenzylation resulted in the target aziridinecyclooctanediol.
