SULFUR-CONTAINING PHOSPHOLIPID DERIVATIVES

The present invention provides a lipid compound comprising at least one non-polar moiety and a polar moiety, wherein each or at least one non-polar moiety is of the formula X-Y-Z-, wherein X is a hydrocarbyl chain, Y is selected from at least one of S, Se, SO2, SO, and O, and Z is an optional hydrocarbyl group, wherein the polar moiety is of the formula -[C(O)]mPHG, wherein PHG is a polar head group, and wherein m is the number of non-polar moieties.

INSECT SEX PHEROMONES. STEREOSELECTIVE SYNTHESIS OF SEVERAL (Z)- AND (E)-ALKEN-1-OLS, THEIR ACETATES, AND OF (9Z,12E)-9,12-TETRADECADIEN-1-YL ACETATE

Several female sex pheromone components produced by moths belonging to the order of Lepidoptera, and potential attractants of Dacus oleae (Diptera:Tripetidae) have been synthesized in high chemical and stereoisomeric purity by improved acetylenic routes involving alkylation of lithium 1-alkyn-1-ides in HMPT, followed by (Z) and (E) highly stereoselective reduction of the derived internal alkynes.Particular care has been paid to optimize the parameters of the reactions used and to evaluate the chemical and isomeric purity of the reaction products.The compounds synthesized include (Z)- and (E)-5-nonen-1-ol, (Z)- and (E)-7-dodecen-1-yl acetate, (Z)- and (E)-7-teradecen-1-yl acetate, (Z)- and (E)-7-nonen-1-ol, (Z)- and (E)-9-tetradecen-1-yl acetate, (Z)- and (E)-10-tetradecen-1-yl acetate, (Z)- and (E)-11-tetradecen-1-yl acetate.Pure (Z)-6-nonen-1-ol, which is an attractant of olive fruit fly, D. oleae, and very probably, a constituent of the sex pheromone of females of this insect, has been prepared by a rather efficient copper-catalyzed reaction between (Z)-3-hexen-1-ylmagnesium bromide and oxetane. (9Z,12E)-9,12-Tetradecadien-1-yl acetate, which is the pheromone of Anagasta kuenniella, Ephestia elutella, Cadra figulella, Spodoptera exigua, S. litura, and a component of the sex pheromones of several other Lepidoptera, has been conveniently prepared by using the copper-catalyzed coupling reaction between (E)-1-chloro-2-butene and 10-tetrahydropyranyloxy-1-decenylmagnesium bromide, followed by acetylation and Z-stereoselective reduction of the derived 1,4-enyne.All syntheses have been conducted on a scale to yield less than 50 mmol of the pure sex pheromone components, but seem adaptable for much larger quantities.
