摘要:
                                The ring transformation of cyclic ketones with a carbonyl function at the side chain under acetalization conditions (BF3/ethylene glycol) was studied.  The results suggested that this reaction proceeds via acetal pathway as a cis-Cyclohexane-1,2-diol was found to be more effective than cis-Cyclohexane-1,2-diol was found to be more effective than ethylene glycol for this ring transformation.
