Volatile ketones from interdigital glands of black-tailed deer,Odocileus hemionus columbianus
摘要:
Three volatile ketones, 2-tridecanone, (E)-3-tridecen-2-one and (E)-4-tridecen-2-one were identified in interdigital gland extracts from black-tailed deer, Odocoileus hemionus columbianus. The major compound, (E)-3-tridecen-2-one, inhibited the growth of several species of fungi and grampositive bacteria. The bacterium, Propionibacterium acnes, and the fungus, Trichophyton mentagrophytes required a minimum concentration (MIC) of 12.5 mu g/ml and 25 mu g/ml, respectively, for inhibition. (E)-3-Tridecen-2-one represents a new class of lipid antibiotics found on animal skin. The second major compound is this secretion, 2-tridecanone, was not active against any of the organisms tested.

The reductive decarboxylation of α-alkenyl derivatives of allyl-β-ketoesters was achieved by use of palladium(0) catalyst generated in situ from Pd(OAc)2 and PPh3, with triethylammonium formate as the hydride source, in THF. The reaction proceeds smoothly and cleanly, with linear alkenyl derivatives of allyl-β-ketoesters, to afford (E)-3-alkenones in good to excellent yields (73–92%) and high stereoselectivity
