摘要： 1,3-oxazin-4-ones of formula (I) wherein W represents -NR6; R1 represents thiophene optionally substituted by one to three groups which may be the same or different selected from halogen, hydroxy, lower alkyl, lower haloalkyl, lower alkoxy, lower haloalkoxy, -S(O)¿n?R?7, -CO¿2R7, COR7, cyano, nitro and phenoxy; R2 represents hydrogen, lower alkyl, lower haloalkyl, alkoxyalkyl, lower alkenyl, lower haloalkenyl, alkoxyalkenyl, -CHO, -COR7, -CO2R7, -CH2NO2, and lower alkyl which is substituted by a group selected from -S(O)mR7 and -OCOR7; R3 represents phenyl optionally substituted by one to five groups which may be the same or different selected from halogen, lower alkyl, lower haloalkyl, lower alkoxy, lower haloalkoxy, -S(O)¿n?R?7, -CO¿2R7,-COR7, cyano, nitro, -OH, phenoxy, -NR8R9 and -SF¿5?; or a cycloalkyl group containing from three to six carbon atoms, optionally substituted by lower alkyl, lower haloalkyl or one or more halogen atoms which may be the same or different; R?4 and R5¿ independently represent lower alkyl; and their use as herbicides.

摘要： 1,3-oxazin-4-ones of formula (I), wherein R1 represents phenyl optionally substituted; R2 represents: a straight- or branched-chain alkyl having from one to ten carbon atoms which is substituted by one or more groups R8 which may be the same or different; a straight- or branched-chain optionally halogenated alkenyl or alkynyl group having up to ten carbon atoms; or a group selected from cyano, -CHO, -COR7, -CO2H, -CO2R?7, -COSR7, -CONR9R10¿, -CH=NOH, -CH=NOR7, -CH=NOCOR7, -CH=NNR?9R10, -CH¿2CN, -CH2NO2 and oxiranyl; R3 represents phenyl optionally susbtituted or R3 represents a first five to seven membered heteroaromatic ring; said first ring being optionally fused and said first ring being linked to the nitrogen atom of the group NR6 via one of the ring carbon atoms; R?4 and R5¿ independently represent lower alkyl; W represents -NR6-; R6 represents hydrogen, lower alkyl, haloalkyl, alkenyl, alkynyl, -COR7 or -CO¿2R?7; and their use as herbicides.

摘要： This invention provides 1,3-oxazin-4-one derivatives represented by general formula (I), in which R1 represents a phenyl group which may be substituted; R2 represents a hydrogen atom or a lower alkyl group; R3 represents a hydrogen atom, a lower alkyl group, an aralkyl group or a phenyl group which may be substituted; R?4 and R5¿ each independently represent a lower alkyl group; and W represents an oxygen atom or a group represented by the formula -N(R6)- in which R6 represents a hydrogen atom, a lower alkyl group, a lower alkenyl group or a lower alkynyl group. There are also provided herbicidal compositions containing the derivatives and N-methylene amino acid ester derivatives represented by general formula (II), in which R?4 and R5¿ each independently represent a lower alkyl group, and R10 represents a lower alkyl group or an aralkyl group, as intermediates for preparing them. The compounds according to the present invention exhibit strong herbicidal activities, and thus they are useful as active ingredients of agricultural chemicals.
