THE SYNTHESIS OF PYRROLIC ANALOGUES OF CHALCONE ON THE BASIS OF 4-ACETYL-3,5-DIMETHYL-1H-PYRROLE-2-CARBOXYLIC ACID AND ITS ETHYL ESTER AND INVESTIGATION OF THEIR ACTIVITY AS PLANTS GROWTH STIMULATORS
A number of new pyrrolic analogues of chalcone containing carboxy- and ethoxycarbonyl groups in the pyrrol ring have been synthesized. When investigating the effect of aqueous and alcoholic solutions of these compounds on barley seed their high efficiency as plants growth stimulators has been revealed.
