Abstract

Lineatin (3, 3, 7-trimethyl-2, 9-dioxatricyclo [3.3. 1. 04q nonane, 1) has been shown to be an aggregation pheromone for the bark beetle Trypodendron lineatum (Oliver), an economically important forest pest which is responsible for significant damage to fallen and cut timber. l The unusual tricyclic acetal structure of 1 has attracted synthetic interest and there have been a number of syntheses reported. 2-8
