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.

Syntheses of two C6 homologating agents 2a and 2f are described. These agents allow direct access to the (Z,Z)-1,4-diene unit 3, a moiety present in a wide number of natural compounds. Compound 2a is prepared in 40% overall yield by selective epoxidation of methoxycyclohexa-1,4-diene followed by oxidative ring cleavage and transacetalization. Compound 2f is obtained in 90% yield by a one-step oxidative dimerization of phosphonium salt 1. A short synthetic application of these two new C6 homologating agents to the synthesis of α-linolenic acid is described.
