Abstract (Z)-11-Hexedecenal 1a and (Z)-13-octadecenenal 2a, components of the sex attractant pheromone of Chilo supressalis, have been synthesized as their ethylene acetals 1b and 2b from cyclododecanone 3, through intermediacy of the C12 ω functionalized acetals 8 and 12.
A cyclododecanone compound is produced in a high reaction rate, with a high conversion of the starting compound, and with a high selectivity to and a high yield of the target compound by isomerizing an epoxycyclododecane compound in the presence of a catalyst comprising lithium bromide and/or lithium iodide, without using a solvent or in a non-polar solvent, in an inert gas atmosphere, while substantially no polymeric compounds having a high boiling temperature is produced.
