<p>1. Preparation process for compounds answering to the Formula (I) : see diagramm : EP0094304,P19,F1 in which the cyclopropane copula is of 1R,cis structure, R represents a hydrogen atom, an alkyl radical containing from 1 to 10 carbon atoms, an easily cleavable radical derived from an alcohol R-OH containing up to 18 carbon atoms, or a radical derived from an alcohol R-OH used in pyrethrinoid series, and : either W represents a hydrogen atom and Y represents a radical CO2 R' or COSR', or W represents a halogen atom Hal and Y represents a radical CO2 R', R' representing a hydrogen atom or a linear, branched or cyclised, saturated or unsaturated alkyl radical, possibly substituted by one of more identical or different functional groups, or an aryl radical containing from 6 to 14 carbon atoms possibly substituted by one or more identical or different functional groups, or a heterocyclic radical possibly substituted by one or more identical or different functional groups, in which Formula (I) the configuration or the double bond is either Z, if W represents a hydrogen atom, or E, if W represents a halogen atom, characterized in that a compound with the Formula (II) : see diagramm : EP0094304,P19,F5 in which the cyclopropane copula is of 1R,cis structure and R retains the previously cited significance, is submitted in the presence of a strong base to the action of a compound with the Formula (III) : see diagramm : EP0094304,P19,F7 in which Y and W retain their previous significance, and A represents a carbonated radical containing up to 18 carbon atoms which links two of the oxygen atoms attached to the phosphorus, so as to obtain the compound with the Formula (I) in which the configuration of the double bond is either Z if W represents a hydrogen atom, or E if W represents a halogen atom, the cyclopropane and the carboxyl of the radical Y being in both cases in cis position in relation to the double bond.</p> |
