Synthesis of 13-oxo-(Z)-9-octadecenoic acid and 15-oxo-(Z)-11-icosenoic acid, arrestants of Oryzaephilus surinamensis L.
Two arrestants of the sawtoothed grain beetle (Oryzaephilus surinamensis L.), 13-oxo-(Z)-9-octadecenoic acid and 15-oxo-(Z)-11-icosenoic acid, were synthesized for the first time by utilizing a Z-selective Wittig reaction.
