Polyunsaturated isobutylamides Related to Citral

Abstract

A group of polyunsaturated acids has been prepared from citral, and the isobutylamides obtained from them have been tested for insecticidal activity. Two of the geometrical isomers of " citrylidene acetic acid " (I; n=l, R=OH), namely, the trans-2,trans-4 and cis-2,cis-4, have been obtained for the first time as crystalline solids.
