This review summarizes the synthesis of pheromones published in the triennium 2002-2004. The syntheses of a total of 66 pheromone compounds (65 from insects, 1 from a crustacean species), belonging to 9 different structural cate-gories, are presented in schemes. New methodologies, but also well-known reactions have been employed to achieve the (in many cases stereoselective) synthesis of the compounds.
