Abstract 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 β- methylene bridge. The substituent in α-position to one of the carbonyl groups can affect ...
