Optical resolutions of 5-alkyl-delta-valerolactones were carried out by derivatization to the diastereomeric amides, in which (R)-(+)-1-(1-naphthyl)ethylamine or (S)-(-)-1-phenylethylamine were used as resolving agents. Optically active 5-fluoroalkanols, useful intermediates for fluorinated ferroelectric liquid crystals, were derived from the resolved lactones in four steps without racemization.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Computed Properties of C9H16O2, you can also check out more blogs about3301-94-8

The use of an amidine of formula (I) and/or a conversion product thereof as a catalyst for the crosslinking of a composition based on silane group-containing polymers. The amidine of formula (I) and the conversion products thereof are essentially odourless at room temperature and non-volatile and accelerate the crosslinking of the composition very well without impairing the storage stability of the composition, and are very compatible in the composition. As a result, the compositions do not have a tendency to separate, migrate or evaporate the catalyst.

Asymmetrically substituted 6I-VII-O-t-butyldimethylsilyl(TBDMS)-3I-VII-O-ethyl-2I-VII-O-methyl-beta-cyclodextrin (MeEt-CD) and 6I-VII-O-TBDMS-2I-VII-O-ethyl-3I-VII-O-methyl-beta-cyclodextrin (EtMe-CD) were synthesised to evaluate the role of the substitution pattern in positions 2 and 3 on the enantioselectivity, in particular in view of their application to routine analysis in fast enantioselective gas chromatography (Es-GC). The chromatographic properties and enantioselectivities of the new derivatives were tested by separating the enantiomers of a series of medium-to-high volatility racemates in the flavour and fragrance field, and compared to those of the corresponding symmetrically substituted 6I-VII-O-TBDMS-2I-VII,3I-VII-O-methyl-beta-CD (MeMe-CD) and 6I-VII-O-TBDMS-2I-VII,3I-VII-O-ethyl-beta-CD (EtEt-CD), and were then applied to analysis of real-world essential oil (e.o.) samples. A new synthetic process including the sonochemical approach to obtain synthetic reproducibility and significant yields of the per-substituted derivatives with acceptable reaction times was developed. The results show that asymmetrically substituted methyl/ethyl CDs compared to the methyl or ethyl symmetrical derivatives in general provide better enantioselectivity in terms of both enantiomer resolution and number of separated chiral compounds, and show how the substitution pattern in positions 2 and 3 of the CD ring can influence the separation. Moreover, these new CD derivatives with better enantioselectivity are also shown to be very useful in routine analysis for the exhaustive control of samples containing several chiral characterizing markers in a single run.

A dynamic headspace (DHS) with DVB/CAR/PDMS trapping materials was coupled to a gas chromatography-mass spectrometry for the separation and identification of volatile-flavor compounds in bos grunniens (yak) milk. The principal components analysis coupled with response surface methodology optimized the main variables of the device (10 g sample quality, 5 min desorption time, 3.0 g adding sodium chloride, 72 C extraction temperature, 28 min pre-equilibrium time and 86 min extraction time). Total 235 volatile components were identified. The limit of detections and quantifications of volatile components were 0.01?5.35 mg kg?1 and 0.01?9.41 mg kg?1, respectively, with relative standard deviation from 0.2% to 6.4%. The method performed well during volatile-flavor components analysis from the yak milk sample, producing excellent extraction parameters for the volatile components. Eighty-two volatile components identified in yak milk belonged to a broad range of chemical classes (ketones, aldehydes, aromatics, acids, alkanes, and estes), and 73 of them were at trace levels. Meanwhile, using gas chromatography-olfactometry technique, 11 volatile components were identified as contributors to the aroma of yak milk. In conclusions, a sensitive, convenient and reliable method was developed for the accurate determination of volatile-flavor compounds in yak milk utilizing DHS-GC/MS analyses.

A systematic approach for the characterisation of the most important aroma-active compounds in a commercial native cold-pressed rapeseed oil on the basis of the Molecular Sensory Science Concept, consisting of aroma extract dilution analysis (AEDA), identification experiments by gas chromatography?olfactometry and gas chromatography?mass spectrometry, stable isotope dilution analysis (SIDA), calculation of odour activity values (OAVs), and recombination experiments, was performed. Forty-nine aroma-active compounds, isolated by thin layer distillation, were identified with a flavour dilution factor ?8 during AEDA and headspace AEDA, 23 thereof reported in native cold-pressed rapeseed oil for the first time. Twenty-three odorants were quantitated via SIDA revealing for 11 compounds concentrations above their respective odour thresholds. Thereby, 2-isopropyl-3-methoxypyrazine, dimethyl trisulphide, dimethyl sulphide, butanoic acid, and octanal showed the highest OAVs (ratio of concentration divided by respective odour threshold). For data validation, a reconstitution model was prepared by mixing the odorants in their natural occurring concentrations in an odourless oily matrix showing an aroma profile very similar to the profile of the original rapeseed oil, confirming that all key aroma compounds were identified and quantitated successfully.

Synthetic Route of 3301-94-8, Because a catalyst decreases the height of the energy barrier, its presence increases the reaction rates of both the forward and the reverse reactions by the same amount. 3301-94-8, Name is 6-Butyltetrahydro-2H-pyran-2-one, molecular formula is C9H16O2.

Previous studies have shown that delta-octalactone is an important component of the tsetse-refractory waterbuck (Kobus defassa) repellent odour blend. In the present study, structure-activity comparison was undertaken to determine the effects of the length of the side chain and ring size of the lactone on adult Glossina pallidipes and Glossina morsitans morsitans. The responses of the flies to each compound were studied in a two-choice wind tunnel. Increasing the chain length from C3 (delta-octalactone) to C4 (delta-nonalactone) enhanced repellency to both species (G. pallidipes from 60.0 to 72.0%, and G. m. morsitans from 61.3 to 72.6%), while increasing the ring size from six (delta-octalactone) to seven members (epsilon-nonalactone) changed the activity from repellency to attraction that was comparable to that of the phenolic blend associated with fermented cow urine (p > 0.05). Blending delta-nonalactone with 4-methylguaiacol (known tsetse repellent) significantly (p < 0.05) raised repellency to 86.7 and 91.7% against G. pallidipes and G. m. morsitans respectively. Follow-up Latin Square Designed field studies (Shimba hills in coastal areas in Kenya) with G. pallidipes populations confirmed the higher repellence of delta-nonalactone (with/without 4-methylguaiacol) compared to delta-octalactone (also, with/without 4-methylguaiacol). The results show that subtle structural changes of olfactory signals can significantly change their interactions with olfactory receptor neurons, and either shift their potency, or change their activity from repellence to attraction. Our results also lay down useful groundwork in the development of more effective control of tsetse by 'push', 'pull' and 'push-pull' tsetse control tactics.

Hydrogen borrowing catalysis serves as a powerful alternative to enolate alkylation, enabling the direct coupling of ketones with unactivated alcohols. However, to date, methods that enable control over the absolute stereochemical outcome of such a process have remained elusive. Here we report a catalytic asymmetric method for the synthesis of enantioenriched cyclohexanes from 1,5-diols via hydrogen borrowing catalysis. This reaction is mediated by the addition of a chiral iridium(I) complex, which is able to impart high levels of enantioselectivity upon the process. A series of enantioenriched cyclohexanes have been prepared and the mode of enantioinduction has been probed by a combination of experimental and DFT studies.
