The reaction of benzyl, methyl and phenyl azide, with olefins substituted by three electron-withdrawing groups, has been studied. This reaction gives in certain cases only one triazoline (single orientation of the cycloaddition). In other cases, a mixture of a triazoline and a diazocompound (double orientation of the cycloaddition) is obtained. The structure assignment of the triazolines is confirmed

Total synthesis of anhydro levuglandin D2 [9-acetyl-8-formyl-5(Z),9(E),11(E)-hepta-decatrienoic acid] confirms the structure assigned to this 9,10-seco prostanoic acid product from solvent induced rearrangement of the prostaglandin endoperoxide PGH2 in aqueous solution.
