Дослiдження продуктiв реакцiї трикомпонентної конденсацiї дициклопентано[b,e]пiридинового кiльця

Abstract

Carrying out the chromatomass-spectrometry analysis of products of the reaction of three component condensation, we have found that diarylidenecyclopentanones are buy-products in the synthesis of dicyclopentapyridines, and the intermediate products are their imines. On the basis of the results of chromatomassspectrometry analysis of the reactionary mixture, the method of synthesis of hexahydrobicyclopenta[b,e]pyridines is improved, and the mechanism of three-component condensation is described.
