Turkish Journal of ChemistryChemistry of Bicyclic Endoperoxides Derived from Dihydropyridine Derivatives: Attempted Synthesis of Polyhydroxypiperidine DerivativesMetin BALCI2, 1Department of Chemistry, Atatürk University, 25240 Erzurum-TURKEY 2Department of Chemistry, Middle East Technical University, 06531 Ankara-TURKEY e-mail: esalamci@atauni.edu.tr, mbalci@metu.edu.tr Abstract: To achieve the synthesis of azasugar derivatives with the utilization of singlet oxygen, pyridine was used as the starting material. The reduction of pyridine followed by a singlet oxygen reaction afforded cyclic aza-endoperoxides (14 and 16). However, many attempts were made to convert the aza-endoperoxides to the corresponding di- and triacetates without success. However, the base-catalyzed rearrangement of 14 gave unprecedented rearrangement products 23 and 24. Key Words: Azasugar derivatives, amino sugars, singlet oxygen, bicyclic endoperoxides
