Conclusions

For a number of substituted vic-cycloheptenediols the chair conformation with a transdiequatorial orientation of hydroxyl groups is suggested by the data of PMR in CDCl3. The data of IR and Raman spectra of dilute solutions of these compounds in CCl4, indicate the possibility of multiple conformations due to the different orientation of OH groups forming intramolecular hydrogen bonds or, depending on the nature of substitution, in ‘twist boat’ forms.
