The toxic hallucinogen 25B-NBOMe is very rapidly degraded by human liver microsomes and has low oral bioavailability. Herein we report on the synthesis, microsomal stability, and 5-HT2A/5-HT2C receptor profile of novel analogues of 25B-NBOMe modified at the primary site of metabolism. Although microsomal stability could be increased while maintaining potent 5-HT2 receptor agonist properties, all analogues had an intrinsic clearance above 1.3 L/kg/h predictive of high first-pass metabolism.

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.

Tetrahydrofurans functionalized at the C2 or C3 position (alcohols, esters, amine, ether, acetal) are cleaved with RCOCl/NaI (R = Me, tBu) in acetonitrile to give regioselectively trifunctionalized derivatives. In all cases the cleavage occurs mainly or exclusively at the C-O bond the most remote from the functional group.

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.COA of Formula: C4H8O2, you can also check out more blogs about453-20-3

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.

Hydrolases showing high enantioselectivity towards three racemic alcohols (1-methoxy-2-propanol, 3-hydroxy-tetrahydrofuran, 3-butyn-2-ol) and pantolactone were identified by a step-wise screening procedure. Initially, those biocatalysts, which exhibited hydrolytic activity towards the corresponding acetates or butyrates, were selected out of >100 enzymes. Here, rapid screening was performed in a pH-indicator-based format in microtiter plates. Subsequently, enantioselectivity of active hydrolases was determined in small scale reactions (?1 mg substrate per reaction) by means of gas chromatography using chiral columns. Enzymes exhibiting highest enantioselectivities were then chosen for preparative scale resolution. Using this strategy, at least one suitable hydrolase was found for 3 out of the 4 model compounds examined, allowing efficient kinetic resolution. Moreover, in all cases enantiocomplementary enzymes were identified thus enabling access to both enantiomers of all substrates.

The rotational spectra of nine isotopomers of the 3-hydroxytetrahydrofuran-water complex were recorded using a Fourier transform microwave spectrometer. The spectra are assigned to the networked structure of the complex, with intermolecular hydrogen bonds from the hydroxyl to the water oxygen and from water to the furanose-ring oxygen. Ab initio calculations, at the MP2/6-31G** level, indicate that this is the lowest energy structure of the complex, and it is based on the lowest-energy ring-puckering conformation of the 3-hydroxytetrahydrofuran monomer, C4?,-endo. Stark effect measurements were used to determine the projections of the dipole moment on the principal inertial axes: mua = 1.2 (3) D, mub = 1.8 (2) D, muc = 0.7 (4) D, and mutot = 2.2 (2) D.
