Transformation of 1-alkyl-substituted indene ozonides and the corresponding solvent-derived ozonolysis products to tricyclic peroxides: Isolation and characterization of novel hexoxecane derivatives

Acidolysis of 1-alkyl-substituted indene ozonides 3a,c,d or the corresponding solvent-derived ozonolysis products 5a-d gave the hexoxecane derivatives 4a-d. The structure of the compound 4a was unambiguously established by the X-ray crystallographic analysis, which demonstrated that the hexoxecane 4a is derived from dimerization of molecules of 3a or 5a of the same configuration.
