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.
