The synthesis of the stereoisomeric hexadeca-2,4-dienoic acids and their isobutylamides

Abstract

The four stereoisomeric hexadeca-2,4-dienoic acids have been synthesized together with their isobutylamides and ethyl esters. The four acids, hexadeca-2,4-diynoic, hexadeca-trans-2-en-4-ynoic, hexadeca-trans-4-en-2-ynoic, and hexadeca-cis-4-en-2-ynoic acids were obtained as intermediates. The insecticidal activities of the isobutylamides of these acids have been determined.
