Pheromones 80. Synthesis of (S)-(+)-manicone and (S)-(+)-normanicone, mandibular gland constituents of myrmicine ants

Article abstract of DOI:10.1055/s-1991-26515

Optically active (4E,6S)-(+)-4,6-dimethyloct-4-en-3-one (10a), manicone, and (3E,5S)-(+)-3,5-dimethylhept-3-en-2-one (10b), normanicone, the biologically active stereoisomers of mandibular gland alarm pheromone components of Manica ants, were synthesized by three different routes starting from (S)-(-)-2-methyl-butan-1-ol (1).
