Sex pheromone biosynthesis in the female olive fruit-fly. Double labelling from [18O2]-dioxygen into 1,7-dioxaspiro[5.5]undecane.

Mary T Fletcher et al.

Chemical communications (Cambridge, England), (12)(12), 1302-1303 (2002-07-12)

The demonstration that both oxygen atoms of 1,7-dioxaspiro[5.5]undecane (1), the sex-pheromone of the female olive fly, originate from dioxygen, strongly implicates monooxygenase mediated processes in assembly of (1), and reveals unexpected complexity in the formation of its nine-carbon precursor.

Inclusion of the main pheromone component of Dacus oleae, 1,7-dioxaspiro[5,5]undecane, in beta-cyclodextrin.

N Rysanek et al.

Acta crystallographica. Section C, Crystal structure communications, 52 ( Pt 11), 2932-2936 (1996-11-15)

The complex beta-cyclodextrin-1,7-dioxaspiro[5,5]undecane nonahydrate, C42H70O35.C9H16O2.9H2O, belongs to the class of beta-cyclodextrin dimeric-type complexes. The racemic guest molecule is present in a disordered position. Both enantiomers are located in two different regions inside the channel formed by the host dimers.

Spiroacetal biosynthesis: (+/-)-1,7-dioxaspiro[5.5]undecane in Bactrocera cacuminata and Bactrocera oleae (Olive Fruit Fly).

Brett D Schwartz et al.

Organic letters, 7(6), 1173-1176 (2005-03-12)

[reaction: see text] A biosynthetic scheme rationalizing the formation of (+/-)-1,7-dioxaspiro[5.5]undecane (5) in the fruit fly species Bactrocera cacuminata and Bactrocera oleae (olive fruit fly) is presented. Incorporation studies with deuterium-labeled keto aldehyde (10), 1,5-nonanediol (11), and 1,5,9-nonanetriol (12), and

Analyzing diurnal and age-related pheromone emission of the olive fruit fly, Bactrocera oleae by sequential SPME-GCMS analysis.

Anat Levi-Zada et al.

Journal of chemical ecology, 38(8), 1036-1041 (2012-09-04)

The olive fruit fly, Bactrocera oleae (Diptera: Tephritidae), uses 1,7-dioxaspiro[5.5]undecane ("olean"), produced primarily by females, as a sex pheromone. We used sequential solid phase microextraction-gas chromatography mass spectrometry (SPME-GCMS) analysis to show that female olive flies release about 1000 ng

Energetics of oxaspirocycle prototypes: 1,7-dioxaspiro[5.5]undecane and 1,7,9-trioxadispiro[5.1.5.3]hexadecane.

Abby Jones Weldon et al.

The Journal of organic chemistry, 71(24), 9212-9216 (2006-11-18)

The relative gas-phase energetics of several low-lying isomers of 1,7-dioxaspiro[5.5]undecane and 1,7,9-trioxadispiro[5.1.5.3]hexadecane have been calculated with second-order Mller-Plesset perturbation theory and basis sets as large as aug-cc-pVQZ. Relative energies in THF, dichloromethane, acetone, and DMSO have been estimated with corrections

Non-covalent interactions in the crystallization of the enantiomers of 1,7-dioxaspiro.

S Makedonopoulou et al.

Acta crystallographica. Section B, Structural science, 57(Pt 3), 399-409 (2001-05-25)

The enantiomers of racemic olive fly sex pheromone 1,7-dioxaspiro[5.5]undecane (1) have been isolated by crystallization with enantiospecific cyclodextrin hosts: (S)-(1) crystallizes with heptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin (TMbetaCD) and (R)-(1) with hexakis(2,3,6-tri-O-methyl)-alpha-cyclodextrin (TMalphaCD). The crystal structure of TMbetaCD/(S)-(1) from synchrotron radiation data at 100
