A nine carbon homologating system for skip-conjugated polyenes
摘要:
Ozonolysis of Z,Z,Z-cylonona-1,4,7-triene leads to a 1,9-difunctionalised Z,Z-3,6-nonadiene which is readily converted into a range of polyunsaturated pheromones and fatty acids. (C) 2014 Elsevier Ireland Ltd. All rights reserved.

Facile and efficient chemical syntheses of (3Z,6Z,9Z)-3,6,9-nonadecatriene and homologues from commercially available alpha-linolenic acid [(9Z,12Z,15Z)-9,12,15-octadecatrienoic acid] are reported. These straight-chain homoconjugated trienes are common sex pheromone and attractant components for many lepidopterous insect pests. The metal-catalyzed cross-coupling reactions between (9Z,12Z,15Z)-9,12
