<p>Substituted aminoquinazoline (thione) derivative, intermediate for preparing thereof, pest regulator and pest control method In the present invention, there is disclosed a substituted aminoquinazoline (thione) derivative of the general formula I or a salt thereof, wherein R represents a hydrogen atom, a hydroxyl group, a formyl group, an alkyl group containing 1 to 12 carbon atoms, a haloalkyl group having 1 to 6 carbon atoms, a hydroxyalkyl group containing 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an optionally substituted aminoalkyl group containing 1 to 6 carbon atoms, an optionally substituted aminocarbonyl group, an optionally substituted phenylalkyl (containing 1 to 3 carbon atoms), an optionally substituted phenylalkynyl group (having 1 to 3 carbon atoms) and the like groups, Re1 denotes 5- to 6-membered heterocyclic ring containing 1 to 3 hetero atoms being selected from the group consisting of an oxygen atom, a sulfur atom and a nitrogen atom, Y represents an oxygen atom or a sulfur atom, Z denotes a group of the general formula -N=C(Ri2) or of the general formula -N(Ri3)-CH(Ri2)-, in which Ri2 and Ri3 represents a hydrogen atom, an alkyl group containing 1 to 6 carbon atoms or the like, X denotes a bromine atom, an iodine atom, a hydroxyl group, a cyanide group, an alkyl group containing 1 to 6 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, an optionally substituted aminocarbonyl group or a phenoxy group or the like groups, and n is an integer 0 through 4. There is also disclosed a pest regulator containing as an active component the above-described aminoquinazoline (thione) derivative or a salt thereof. Further disclosed is a method of controlling pest, which method comprises applying the aforementioned regulator to corresponding plants or soil.</p> |
