摘要

FIELD: organic chemistry, heterocyclic compounds. SUBSTANCE: invention relates to substituted heterocyclic compounds of the formula (I) where E - oxygen or sulfur; A means CR or N; R - hydrogen or lower alkyl; D completes 5- or 6-membered nonaromatic heterocyclic ring that has optionally additional heteroatoms taken from oxygen, nitrogen or sulfur and can be substituted with C1-10-alkyl or phenyl; R and R - hydrogen, alkyl, alkenyl, alkynyl, cyclopropyl, cyclopropylmethyl, cyclohexyl, adamantyl, phenyl or pyridyl; or R and R together with nitrogen atom to which they are bound form morpholine ring; Z - halogen, cyano-group, NHOH, SF5, acylamino-group, COOR7, NR13R , dibenzylaminosulfonyl; or Z - alkyl, alkenyl, alkoxy, phenoxy, alkylthio, alkylsulfonyl or CO-alkyl and each group can be substituted with halogen or C1-6-alkoxy- -group; R is C1-10-alkyl; R and R - hydrogen or SO2--alkyl; m = 0, 1 or 2. Compounds of the formula (I) show activity against broad order of weeds including monocotyledonous and dicotyledonous species. EFFECT: improved method of synthesis, enhanced effectiveness of compounds. 15 cl, 9 dwg, 17 tbl, 102 ex
