The synthesis of 30 heterocyclic 1,3-dicarbonyl compounds, the corresponding hydroperoxides and the 10 alcohols, their characterization, and the limitations of the procedure are described. In addition, the mechanism of the hydroperoxidation and the redox decomposition of the hydroperoxides are discussed. http://www.mdpi.com/1420-3049/16/11/9562 journal article Molecular Diversity Preservation International 2011-11 VoR application/pdf Molecules 11 16 9562 9581 14203049 https://kumadai.repo.nii.ac.jp/record/26605/files/Molecules-,2011,16,9562-9581-full version.pdf http://hdl.handle.net/2298/25261 https://kumadai.repo.nii.ac.jp/records/26605 eng 22089863
