Abstract: Anew method for the synthesis and monoprotection of 2,6-heptanedione(2) is reported. 3, 7-Dimethyl-2,7-octadien-l- yl propanoate (1), the main component of San Jose Scale's sex pheromone, was synthesized by a two-step Wittig reaction from 6-(1,3-dioxolan-2-yl)-2-heptanone (3) in 31% yield. Z : E=19 : 81. The total yield is 11%.
