摘要
On a series of 44 alicyclic 1,5-di- and 1,3,5-triketones was studied the influence of various structural factors (size of the 5-7-membered ring, positions of the substituents) on the capability for intramolecular aldol condensation and on its direction. The most prone to this reaction are compounds possessing a 6-membered cycle and a substituent in the beta -methylene bridge. The substituent in alpha -position to one of the carbonyl groups can affect the reaction in two ways depending on the degree of shielding of this position.
