Simple and efficient routes to substituted oxazolidine and spiro-oxindole systems by one-pot synthetic strategies

Simple and efficient strategies towards the synthesis of substituted spiro-oxindole and oxazolidine systems by one-pot multi-component catalyst-free reactions utilising aryl aldehydes and alpha-amino acids have been developed. Owing to their complicated structure and ring strain spiro-oxindole moieties are not easily synthesised. In either route 1,3-dipolar cycloadditions involving non-stabilised azomethine ylides as intermediates, generated in situ from amino acids and aldehydes, with the dipolarophile present in the reaction mixture viz. (E)-beta-nitrostyrene, were utilised. The route to substituted oxazolidines involved cycloaddition to the C=O bond of a second molecule of the aldehyde.

Consequences of the formation of 3,4-dimethyl-5-phenyl-1,3-oxazolidine on the analysis of ephedrines in urine by gas chromatography and a new method for confirmation as N-trifluoroacetyl-O-t-butyldimethylsilyl ether derivatives

The compound 3,4-dimethyl-5-phenyl-1,3-oxazolidine can appear as an artifact during the gas chromatographic analysis of ephedrines. Its presence is a risk for doping control and forensic analyses. An evaluation about the consequences of its formation showed the possibility of a false positive for ephedrine, a false negative for pseudophedrine and increased uncertainty in the quantitative approach. Misinterpretations can be avoided with the observation of fragments m/z 56 and 71 in the ephedrine mass spectrum during GC-MS analysis and also by the formation of N-TFA-O-TBDMS derivatives prior to GC analysis. These N-TFA-O-TBDMS derivatives lead to an increase in the number and mass of diagnostic ions, meet the identification criteria, and provide an improvement in chromatographic resolution, allowing the separation of the ephedrines.

Intracellular pH sensing using polymeric micelle containing tetraphenylethylene-oxazolidine

A novel amphiphilic copolymer consisting of tetraphenylethylene-oxazolidine (TPE-OX) as a pH-sensitive chromophore and poly(ethylene glycol) methyl ether methacrylate (PEGMA) as a water-soluble chain has been well designed and synthesized. A self-assembled polymeric micelle based on the copolymer exhibited clear dual-emission switching between cyan and red with a decrease of pH value in Tris-HCl buffer solution due to the extended conjugation and emerging intramolecular charge transfer effect when opening the spiro-ring of OX moiety. Fluorescence imaging of HepG2 cells stained by the polymeric micelle shows switched luminescence from cyan to red with high selectivity and contrast, indicating that the polymeric micelle was an effective probe for intracellular pH detection. Additionally, the red emission of the polymeric micelle in lysosomes can reversibly switch back to the original cyan emission in response to the two lysosomal activity inhibitors chloroquine and bafilomycin, which demonstrates that the polymeric micelle has potential applications in detecting the activity of lysosomal and further autophagy in cancer cells.

Expanding the Scope of the Cleavable N-(Methoxy)oxazolidine Linker for the Synthesis of Oligonucleotide Conjugates

Oligonucleotides modified by a 2 ‘-deoxy-2 ‘-(N-methoxyamino) ribonucleotide react readily with aldehydes in slightly acidic conditions to yield the corresponding N-(methoxy)oxazolidine-linked oligonucleotide-conjugates. The reaction is reversible and dynamic in slightly acidic conditions, while the products are virtually stable above pH 7, where the reaction is in a ”switched off-state”. Small molecular examinations have demonstrated that aldehyde constituents affect the cleavage rate of the N-(methoxy)oxazolidine-linkage. This can be utilized to adjust the stability of this pH-responsive cleavable linker for drug delivery applications. In the present study, Fmoc-beta-Ala-H was immobilized to a serine-modified ChemMatrix resin and used for the automated assembly of two peptidealdehydes and one aldehyde-modified peptide nucleic acid (PNA). In addition, a triantennary N-acetyl-d-galactosamine-cluster with a beta-Ala-H unit has been synthesized. These aldehydes were conjugated via N-(methoxy)oxazolidine-linkage to therapeutically relevant oligonucleotide phosphorothioates and one DNA-aptamer in 19-47% isolated yields. The cleavage rates of the conjugates were studied in slightly acidic conditions. In addition to the diverse set of conjugates synthesized, these experiments and a comparison to published data demonstrate that the simple conversion of Gly-H to beta-Ala-H residue resulted in a faster cleavage of the N-(methoxy)oxazolidine-linker at pH 5, being comparable (T-0.5 ca 7 h) to hydrazone-based structures.

Stereoselective Photooxidations by the Schenck Ene Reaction

150 years after the first report of an organic reaction with singlet oxygen (O-1(2)) and 70 years after the discovery of the singlet oxygen-ene reaction (Schenck reaction) with alkenes, this allylic photooxidation has matured to a powerful transformation that enables access to diverse sets of allyl alcohol derivatives from ubiquitous starting materials. The reaction exhibits high sustainability (100% atom economy, use of simple alkenes, air, metal-free catalyst and visible light). Good levels of chemo-, regio-, and stereocontrol were observed in the synthesis of various fine chemical building blocks and biologically active molecules. This Minireview provides an overview of the key strategies that enable stereoselective oxygen-ene reactions in the context of complex molecule syntheses including photooxygenations of functionalized alkenes, cycloalkenes, and auxiliary-based methods.

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. you can also check out more blogs about 84793-24-8. Computed Properties of C16H19NO5.

Molecular Motion in Frozen Phospholipid Bilayers in the Presence of Sucrose and Sorbitol Studied by the Spin-Echo EPR of Spin Labels

Electron spin echo (ESE) spectroscopy, a pulsed version of electron paramagnetic resonance (EPR), was applied to spin-labeled stearic acids in phospholipid bilayers hydrated in the presence of sucrose and sorbitol, which are known for their cryoprotective action on biological membranes. The phospholipids were 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) and 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC). Stearic acids were labeled by nitroxide 4,4-dimethyl-oxazolidine-1-oxyl (DOXYL) attached rigidly at either the 5th or 16th specific carbon positions. ESE detects fast stochastic small-angle restricted molecular rotations (stochastic molecular librations) with correlation times on the nanosecond timescale. These motions are believed to have the same nature as the anharmonic motions of hydrogen atoms in biological substances detected by neutron scattering and Mossbauer spectroscopy, which become active above 200 K. To ensure that the echo decays indeed originate from fast stochastic molecular librations, a three-pulse stimulated spin echo was employed. It was found that the presence of sucrose or sorbitol suppresses the observed molecular motions. The observed effect was nearly the same for both label positions, indicating that the motions are similarly suppressed near the bilayer surface and in the bilayer interior. This finding suggests non-specific interactions of sugars with bilayer surface, which are likely to influence only the bulk physical properties of hydrated membranes. The results obtained show the usefulness of spin-echo EPR of spin labels when applied to investigate the molecular mechanisms of action of cryoprotective agents on biological systems.
