Patent

CA 2147275

The present invention is directed to pyrimidine derivatives represented by a general formula (I) having a herbicidal and fungicidal activities: Image (I) wherein R1 and R2 are each independently hydrogen; alkyl; alkenyl; alkynyl; phenyl; cyano; COOR9 ; OR10 ; SR11 ; OCOR12 ; amino, Z1p (=Z2) (Z3R13)(Z4R14) or they form in together oxo, thioxo, cyclic ketal, cyclic thioketal, =CR15R16 , =NR17 , =NNR18R13 , =NOR20 ; or any spiro ring selected from the group consisting of: Image , Image , Image , Image , and Image R3 and R5 are each independently hydrogen; halogen; alkyl; alkenyl; alkynyl; phenyl; cycloalkyl; S(O) m R21 ; NR22R23 ; NR24NR25R26 ; OR27 ; cyano; COOR28 ; CONR29R30 ; PZ5(OR31)(OR32) or phenyl; R4 is hydrogen; halogen; amino; cyano; alkyl; alkenyl; alkynyl; phenyl; cycloalkyl; COOR33 ; COR34 ; CONR35R36 ; OR37 ; S(O)pR38. However, when R4 is hydrogen, R3 and R5 are different and R4 combines with R3 or R5 and a pyrimidine ring to form a condensed ring represented by the following general formulas: Image or Image R6 and R7 are each independently hydrogen; halogen; alkyl; alkenyl; alkynyl; phenyl; cycloalkyl; S(O) r R39 ; OR40 ; COOR41 ; CONR42R43 ; amino; nitro or cyano. However, R6 and R7 are not hydrogen at the same time. R8 may be same or different, representing halogen; alkyl; alkenyl; alkynyl; phenyl; cycloalkyl; S(O)tR44 ; OR45 ; COOR48 ; CONR47R48 ; amino; nitro or cyano; n denotes an integar 0, 1, 2 or 3, with the proviso that R4 is the condensed ring described above in combining with R3 or R5 and a pyrimidine ring when both R1 and R2 are hydrogen.
