In the general formula (I) of the compounds of the invention, R 1, R 2 and R 3 are selected from the group consisting of hydrogen, n-methyl, cycloalkyl, halo-cycloalkyl, cycloalkenyl, halo-cycloalkenyl-piperidine, and -A 1 -Q 1 represents an oxygen or sulfur atom, a parent phenyl or a carbonyl, an alkylene, an alkenylene, an alkynylene piperidine, or a -N (R 4) - substituent of the general formula wherein R 4 is alkylcarbonyl, haloalkylcarbonyl, alkoxy, -carbenyl or at least one substituent substituted phenylcarbonyl piperidine from which the substituents may be monomeric or different, namely, halogen, cyano, nitro, alkyl, haloalkyl, alkenyl, halo alkynyl, alkoxy, haloalkoxy, alkylthio, haloalkylthio, alkylsulfinyl, haloalkylsulfinyl, alkylsulfonyl, haloalkylsulfinyl, mono alkylamino or dialkylamino piperidine, Q1 is a variety of pipettor depending on the interpretation of A1, which is included with Xn and Ymm. R1 and R2, together with the nitrogen to which they are attached, can also form a 4- to 7-membered heterocyclic ringpipe, and Z1 and Z2 are either oxygen or sulfur. (I) ŕ |
