    摘要: Substituted quinazolines of the formula (1):
    wherein:
    R 1 to R 4 are independently H, halo, (Ci-C 4 ) alkyl, branched (C 3 -C 4 ) alkyl, halo (C 1 -C 4 ) alkyl, (Ci-C 4 ) alkoxy, N0 2 , or NH 2 , provided that at least two of R 1 to R 4 are H; Y is H, Cl, X-W-Ar, or O-Alk; X is 0, NR 7 , or CR8 R 9; Z is H, Cl, OCH 3 , CH 3 , or -NR 7- W-Ar, provided that Z can be -NR 7 -W-Ar only if Y is H, Cl, or NR 7 -W-Ar and Z must be -NR 7- W-Ar if Y is H or Cl; R 7 is H, (C 1 -C 4 ) alkyl, or acetyl; R 8 and R9 are independently H, (C 1 -C 4 ) alkyl, halo, or OH; W is an alkylene chain 2 to 6 carbon atoms long, optionally including a carbocyclic ring or substituted with (C 1 -C 3 ) alkyl, phenyl, (C 3 -C 8 ) cycloalkyl, halo, hydroxy, or acetyl; and Ar is imidazolyl; indolyl; thienyl, optionally substituted with CH 3 or Cl; thiazolyl; 1,3-benzodioxolyl; fluorenyl; cyclohexyl (hexahydrophenyl), cyclohexenyl (tetrahydrophenyl), naphthyl, dihydronaphthyl, tetrahydronaphthyl, decahydronaphthyl;
    or a group of the formula (2): where
    R 10 to R 14 are independently H, halo, I, (C 1 -C 10 ) alkyl, branched (C 3 -C 6 ) alkyl, halo (C 1 -C 4 ) alkyl, (Ci-C 4 ) alkoxy, halo (C 1 -C 4 ) alkoxy, phenoxy, substituted phenoxy, phenyl, substituted phenyl, phenylthio, substituted phenylthio, NH 2 , N0 2 , OH, or CN, at least two R 1 to R 4 being H; Alk is (C 2 -C 18 ) alkyl, straight chain or branched;
    or an acid addition salt of a compound of formula (1) provided that:
    if R 1 to R 4 are all H and Y is NR 7- W-Ar, then Ar is naphthyl or a group of formula (2) wherein at least one of R 10 to R 14 is phenyl, substituted phenyl, phenoxy, substituted phenoxy, phenylthio, substituted phenylthio, halo (C 1 -C 4 ) alkyl, or halo (C 1 -C 4 ) alkoxy are plant fungicides, miticides, and insecticides.
