Abstract
FIELD: heterocyclic compounds. SUBSTANCE: product: 5-aryl-1-p-tolyl-4-diphenylmethyl-4-ethoxycarbonylte- trahydropyrrol-2,3-diones of the formulawhere R - H, Br. Synthesis is carried out from the corresponding 5-aryl-1-p-tolyl-3-dipnenylmethoxy-4-ethoxycarbonyl-2,5-dihyd- ropyrrol-2-one by heating at 200-215 C for 30-40 min. The yield, %; m. p., C; empirical formula: for the first compound: 77; 287-288; CHBrNO; for the second compound: 55; 271-272; CHBrNO. Synthesized compounds show antimicrobial activity. EFFECT: improved method of synthesis, increased yields.
