The oxidation with CrO3 of the two isomeric tetrols (I) containing cis-1,2-diol groupings has been investigated. This reaction leads to the hydroxy-ketal III (two isomers), as well as to the hemi-ketals XI and XIV containing a five-membered ring. The mode of formation of these substances is discussed, and our results are related to previous work with α-methylenecyclohexanone dimer (V) carried out by
