As a result of the reaction of resorcinols with dimethyl acetonedicarboxylate under the conditions of the Pechmann reaction derivatives of 4,4′-spirodichroman-2-one were isolated as anomalous condensation products. Their structure was demonstrated by spectral methods. A mechanism was proposed for the formation of the spirodilactone system.
