(Chemical Equation Presented) Limitations of models in total synthesis are illustrated by a study towards the potent cytotoxic macrolide iejimalide B. Although the Yamaguchi protocol allowed for the esterification of elaborate segments, attempted macrolactonization of the seco acid met with failure (see scheme, Boc = tert-butyloxycarbonyl). The assembly of the seco acid involves some of the most advanced applications of the Julia olefination known to date.

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.Recommanded Product: (S)-(-)-alpha-Hydroxy-gamma-butyrolactone, you can also check out more blogs about52079-23-9

453-20-3, Name is 3-Hydroxytetrahydrofuran, belongs to tetrahydrofurans compound, is a common compound. name: 3-HydroxytetrahydrofuranIn an article, once mentioned the new application about 453-20-3.

In this study, the inclusion phenomena of tetrahydrofuran + 3-hydroxytetrahydrofuran + CH4 clathrate hydrates were explored via thermodynamic and spectroscopic approaches. The phase equilibria of the double hydrates – THF + CH4 and 3-OH THF + CH4 clathrate hydrates – were determined by pressure-temperature trace during hydrate formation and dissociation, and the result revealed that the equilibrium pressures were shifted to lower pressure region compared to pure CH4 hydrate. The powder X-ray diffraction patterns revealed that the double hydrates of THF + 3-OH THF formed structure II type clathrate hydrates with CH4. The dispersive Raman spectra of the double clathrate hydrates also exhibited that CH4 can be trapped in both 51264 and 512 cages whereas THF and 3-OH THF were encaged in 51264 cage.

A novel recyclable prolinamide-derived ionic-liquid-supported organocatalyst of asymmetric cross-aldol reactions in aqueous medium has been developed. In its presence, aromatic aldehydes react with cyclic or linear ketones to afford chiral aldol adducts in moderate to high yields and with excellent dr (anti/syn up to 96:4) and ee (81-99%) values that do not tend to decline over ten recycles of the catalyst. Furthermore, it allows a highly enantioselective catalytic synthesis of linear bis-aldols in aqueous medium.

The possibilities offered by a new methodology to determine minor components in edible oils are described. This is based on immersion of a solid-phase microextraction fiber of PDMS/DVB into the oil matrix, followed by Gas Chromatography/Mass Spectrometry. It enables characterization and differentiation of edible oils in a simple way, without either solvents or sample modification. This methodology allows simultaneous identification and quantification of sterols, tocols, hydrocarbons of different natures, fatty acids, esters, monoglycerides, fatty amides, aldehydes, ketones, alcohols, epoxides, furans, pyrans and terpenic oxygenated derivatives. The broad information provided by this methodology is useful for different areas of interest such as nutritional value, oxidative stability, technological performance, quality, processing, safety and even the prevention of fraudulent practices. Furthermore, for the first time, certain fatty amides, gamma- and delta-lactones of high molecular weight, and other aromatic compounds such as some esters derived from cinnamic acid have been detected in edible oils.
