摘要：PROBLEM TO BE SOLVED: To obtain a new compound having a strong herbicidal activity, capable of remarkably reducing a chemical injury to cultivated crops such as rice plants and having a highly selective weeding activity. SOLUTION: This compound is expressed by formula I [wherein, R<1> is a hydrocarbon, carbamoyl, or the like; R<2> and R<3> are each H, an alkyl, or the like; R<4> is a hydrocarbon or a hetero ring; R<5> is H or a (substituted) alkyl; >A<1> -A<2> - is a group expressed by formula II, formula III, or the like (wherein, R<8> is H, a hydrocarbon, or the like); W is O, S, or the like], e.g. 3- allyloxy-1-(1-(3,5-dichlorophenyl)-1-methylethyl)-4-phenylperhydropyri midin-2-one. The compound of formula I is obtained e.g. by reacting a compound of formula IV with 1 mol eq. or more of a compound selected from a group consisting of phosgene, diphosgene and triphosgene. The compound of formula IV is a new compound and is obtained by reacting a compound of formula V (wherein, Y<7> is a lower alkoxy or combined with other Y<7> to become O) with a compound of the formula: [R<4> -W-NH2 ].
