BICYCLIC HYDANTOIN DERIVATIVES, PROCESS FOR PRODUCING THE SAME, AND HERBICIDES CONTAINING THE SAME AS ACTIVE INGREDIENT

摘要

Novel bicyclic hydantoin derivatives having excellent herbicidal activities and a high safety for crops and represented by general formula (1) are produced by, for example, the reaction of an aryl isocyanate derivative represented by general formula (2) with a pipecolic acid derivative represented by general formula (3).
