Housefly, sex attractant

Housefly, sex attractant of, 255 HPLC, 432 Hiickel, Erich, 523 Htickel 4/j + 2 rule, 523... 

An unbranched 9-carbon unit and an unbranched 14-carbon unit make up the carbon skeleton, and these two units must be connected by a double bond. The housefly sex attractant therefore has the constitution ... 

A variation on the preparation of Gilman reagents is to use a Grignard reagent in the presence of a catalytic amount of Cu(I). Zoecon Corporation has developed a synthesis of 150 kg batches of the housefly sex attractant muscalure by treating (Z)-l-bromo-9-octadecene with pentylmagnesium bromide in the presence of catalytic amounts of Cu(I). The starting bromoalkene is easily prepared from the readily available (Z)-9-octadecenoic acid (oleic acid. Section 26.1). Yields of muscalure are nearly quantitative.

The sex attractant by which the female housefly attracts the male has the molecular formula C23H46 Catalytic hydrogenation yields an alkane of molecular formula C23H4g Ozonolysis yields... 

The sex attractant of the common housefly is a hydrocarbon with the formula C23H46. On treatment with aqueous acidic KMn04, two products are obtained, CH3(CH2),2C02H and Cb fCB hCX H. Propose a structure. 

The sex attractant given off by the common housefly is an alkene named muscahtre. Propose a synthesis of muscalure starting from acetylene and any alkyl halides needed. What is the IUPAC name for muscalure ... 

Muscalure 20, the pheromone of the housefly has been prepared from oleic acid or erucic acid, similarly (Z)-l 1-heneicosene 21, the synergist of muscalure was obtained [189]. The intermediate 22 for the pheromone of the Cabbage looper was prepared using (Z)-methyl-4-octenedioate [166bJ, that was obtained by partial ozonolysis of (Z,Z)-l,5-cyclooctadiene. Similarly disparlure 23, the sex attractant of the gypsy moth, has been synthesized by two successive crossed-couplings with (Z)-4-octene dioate [191],... 

Muscalure is the sex attractant of the common housefly (Musca domesticd). 

The sex attractant of the female housefly consumes one mole of hydrogen on catalytic hydrogenation (the molecular formula changes from C23H46 to C23H48). Thus, the molecule has one double bond. The position of the double bond is revealed by the ozonolysis data. 

The occurrence of hydrocarbons (usually mono- and di-alkenes) with an epoxide function group have been reported usually as sex attractants. The sex attractant of the female gypsy moth, Lymantria dispar, was identified as the C18 2-methyl alkane derivative cis-7,S-epoxy-2-methyloctadecane (Bierl et al 1972). For the housefly, M. domestica, a major sex pheromone component is the C23 -alkane epoxide d.v-9,1O-cpoxytricosane (Uebel et al 1978) with a lesser quantity of 9,10-epoxyheptacosane (Mpuru et al., 2001). 

A large series of (Zj-9-alkenes enhanced the releasing effect in conjunction with the optical stimuli of sex attraction resulting from the presence of dummy flies. By themselves, the monoolefins showed little promise for the control of houseflies (45). 

Alkenes are hydrocarbons with carbon-carbon double bonds. Alkenes are sometimes called olefins, a term derived from olefiant gas, meaning oil-forming gas. This term Introduction originated with early experimentalists who noticed the oily appearance of alkene derivatives. Alkenes are among the most important industrial compounds (see Section 7-6), and many alkenes are also found in plants and animals. Ethylene is the largest-volume industrial organic compound, used to make polyethylene and a variety of other industrial and consumer chemicals. Pinene is a major component of turpentine, the paint solvent distilled from extracts of evergreen trees. Muscalure (cw-tricos-9-ene) is the sex attractant of the common housefly. 

The sex attractant of the housefly has the formula C H, . When treated with warm potassium permanganate, this... 

Muscalure, the sex attractant of the common housefly, is cA-tricos-9-ene. Most syntheses of alkenes give the more stable trans isomer as the major product. Devise a synthesis of muscalure from acetylene and other compounds of your choice. Your synthesis must give specifically the cis isomer of muscalure. 

Muscalure is the sex attractant of the common housefly. Flies are lured to traps by filling them with fly bait containing both muscalure and an insecticide. Eating the bait is fatal.
