Neuere Ergebnisse der Chemie von Insektensexuallockstoffen. Synthesen von D,L‐10‐Acetoxy‐hexadecen‐(7‐cis)‐ol‐(1), 12‐Acetoxy‐octadecen‐(9‐cis)‐ol‐(1) („Gyplure”︁) und 1‐Acetoxy‐10‐propyl‐tridecadien‐(5‐trans. 9)

Abstract: Bd. 709Diese stets positive Reaktion von Bombyx mori selbst auf verunreinigte Praparate ist ja auch biologisch verstandlich, da Bombykol ein spezifischer Sexuallockstoff ist, der in der Natur stets mit FraRlockstoffen, Duftstoffen und anderen chemischen Individuen vergesellschaftet vorkommt und trotzdem vom Seidenspinnermannchen wahrgenommen wird. Die Konzentration des Bombykols am Rezeptor betragt an der Verhaltensschwelle 2.102 Molekiile/ccm Luft6). Auch das als 2-trans-Decenon-(9)-saure-( 1) charakterisiert… Show more

“…Ethyl lupininate (Va) was prepared by treatment of ethyl 1-10-dehydrolupininate (IVb),7 obtained from the reaction of IVa (3.0 g, 13 mmol) with ethyl chloroformate (1.4 g, 11 mmol), with sodium borohydride (2.5 g, 66 mmol) in methanol (15 ml) at 5°. The pure desire ester7 was obtained by distillation: yield 0.75 g (57%); bp 79-81°(0.025 mm); nmr (CCh) 4.05 (q, 2, OCH2), 3.0-1.2 (complex, 16, quinolizidine H), and 1.13 (t, 3, CCHg).…”

Found: C, 77.00; H, 9.46; P, 9.42. 1,2,5-Triphenylphospholane 1-Oxide (3).-1,2,5-Triphenylphosphole 1-oxide (5.0 g, 0.015 mol) was dissolved in a 2:1 acetic acid-ethyl acetate mixture. Palladium (0.75 g of 10% palladium on carbon) was added, and the compound was reduced at room temperature and 4 atm.…”

“…The organic layer was separated and the water layer was extracted with toluene. The combined toluene solution was distilled on a spinning-band column to give 28.6 g, (50%): bp 98°(12 mm); ra28d 1.4270; dinitrophenylhydrazone, mp 98-99°( lit.8 mp 100°); nmr (CDCls) 0.23 (t, 1, J = 1.5 Hz), 5.93 (m, 2), 7.49 (m, 2), 7.96 (s, 3), and 8.31 (m, 4). The same procedure was followed with 5-iodo-w-pentyl acetate to give the aldehyde in 40% yield.…”
