Document Type and Number:
WIPO Patent Application WO/2014/206897
Kind Code:
A3
Abstract:
The present invention relates to a process for the cyclopropanation with ethylene carbonate or ethylene sulfate of a compound of formula (II): wherein G is -CN or -COOR in which R is a C1-C4 straight or branched alkyl X and Y are independently selected from the group consisting of hydrogen, fluorine, chlorine, bromine, iodine, R1O- and R1S- wherein R1 is C1-C4 straight or branched alkyl chain.
