3,4-SUBSTITUTED PYRROLE DERIVATIVES

摘要

This invention relates to novel pyrrole derivatives of the general formula II' < IMG > II' wherein R1 is a fragment selected from the group consisting of ¢X,Y,Z(phenyl)!, ¢X,Y,Z(biphenyl)l, ¢U,V,W(pyridyl)!, ¢U,V,W(furyl)! and ¢U,V,W(thienyl)!, wherein X, Y and Z are each independently selected from the group consisting of hydrogen, halogen, C1-C4alkyl, Cl-C3haloalkyl, di(Cl C4alkyl)amino, nitro, cyano, -COO(Cl-C4alkyl), -CON(Cl- C4alkyl)2 and the group -E-R4, where E is -O-, -S-, -SO-or -SO2-, R4 is Cl-C6alkyl which is unsubstituted or substituted by C1-C4alkoxy, C3-C5alkenyl which is unsubstituted or substituted by halogen, C3-C5alkyoyl which is unsubstituted or substituted by halogen or hydroxy, or is ¢X,Y,Z(phenyl)! or -CH2-¢X,Y,Z(phenyl)!; U, V and W are each independently selected from the group consisting of hydrogen, halogen and Cl-C4alkyl, and R2 is -COO(Cl-C6alkyl), -CO(Cl-C6alkyl), -CO-N(C1-C6alkyl)2, cyano, nitro, -SO2-(Cl-C6alkyl), -P(O)-(C1-C6alkoxy)2, -SO-(Cl-C6alkyl) or -SO2-N(Cl-C3alkyl)2. These compounds are useful intermediates in the preparation of certain corresponding N-sulfenylated pyrrole derivatives having microbicidal activity.
