Gy. Ishmuratov et al., Synthesis from 10-undecenoic acid of octadeca-2E,13Z-dienylacetate, a component of the sex pheromones of Synanthedon tipuliformis and Zenzera pyrina, CHEM NAT CO, 36(2), 2000, pp. 207-209
A new synthesis of octadeca-2E, 13Z-dienylacetate from 10-undecenoic acid i
s developed by constructing the carbon framework of the pheromone in the ke
y step and introducing the 2E double bond by Doebner condensation of hexade
c-11-ynal and malonic acid.
