  • 1,3-oxazin-4-one derivative, herbicide containing same, and intermediate for preparing same
    Patent number: 5977025
    Abstract: This invention provides 1,3-oxazin-4-one derivatives represented by following general formula (I): ##STR1## in which R.sup.1 represents a phenyl group which may be substituted; R.sup.2 represents a hydrogen atom or a lower alkyl group; R.sup.3 represents a hydrogen atom, a lower alkyl group, an aralkyl group or a phenyl group which may be substituted; R.sup.4 and R.sup.5 each independently represent a lower alkyl group; and W represents an oxygen atom or a group represented by the formula --N(R.sup.6)-- in which R.sup.6 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 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.
