This invention relates to oxazolidinedione derivatives of general formula (1) and a method of producing the same, wherein R¹ represents a hydrogen atom or a lower alkyl group, and R² represents a hydrogen atom or a lower alkyl group as well. The above compounds serve as an intermediate for the production of benzoxazinone derivatives of general formula(II)selectively in good yields, wherein R¹ represents a hydrogen atom or a lower alkyl group, and R³ represents a hydrogen atom or an alkyl, cyanoalkyl, alkenyl, alkynyl or aralkyl group. Said benzoxazinone derivatives are well-known and useful as a herbicide.

A benzoxazinone compound represented by the formula (I):
wherein R¹ represents a hydrogen atom or an alkyl group, and R² represents a hydrogen atom, an alkyl group, a cyanoalkyl group, an alkenyl group, an alkynyl group or an aralkyl group; a process for preparing the same; and a herbicidal composition comprising the benzoxazinone compound as an active component are disclosed. The above benzoxazinone compounds exhibit a high selectivity for useful crop plants and a strong herbicidal activity with respect to various noxious weeds.
