Oxazolidines as Intermediates in the Asymmetric Synthesis of 3-Substituted and 1,3-Disubstituted Tetrahydroisoquinolines

A diastereoselective mercury(II)-promoted intramolecular cyclization of unsaturated aldehyde via an oxazolidine to prepare C-3-substituted tetrahydroisoquinoline is disclosed. The C-3 stereogenic center is subsequently exploited to create the C-1 stereocenter by coordination of the nudeophilic reagent to the oxygen atom of oxazolidine. Both cis- and trans-1,3-disubstituted tetrahydroisoquinolines can be readily prepared. In addition, when a cationic rhodium complex was used, intramolecular hydroamination was effected, thus avoiding mercury(II) salts and demercuration. The reaction is general and works well using aliphatic and aromatic aldehydes.

Induction of maize glutathione S-transferase by herbicide safener and their effect on enzyme activity against chlorsulfuron

The acetolactate synthase(ALS) activity, glutathione S-transferase(GST) activity and glutathione(GSH) content in maize was investigated in response to treatments with safener (S)-3-dichloroacety1-2,2-dimethyl-4-ethyl-1,3-oxazolidine. When induced by the chiral compound, the GSH content in root and shoot of maize increased 91.10% and 71.66%, respectively, the recovery rate of ALS activity reached 77%, and the GST activity increased 103.77%. The activity of maize GST was also assayed towards chlorsulfuron in vitro; the results showed that the induction of GST activity against chlorsulfuron of 14.54% was obtained. The enhancement of GST activity was found to be concomitant with changes in kinetic constants, which was related directly to the enzyme affinity for the CDNB substrate.

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. SDS of cas: 84793-24-8.

Assessing the Structure of Octastate Molecular Switches Using H-1 NMR Density Functional Theory Calculations

Density functional theory calculations are used to reveal the relationships between the structures, energies, and NMR signatures of an octastate molecular switch composed of a dithienylethene (DTE) unit covalently linked to an indolino[2,1-b]oxazolidine (BOX) moiety through an ethylenic junction. Both the DTE and BOX moieties can adopt open or closed forms. The ethylenic junction can be Z or E, but the latter has been confirmed to be, by far, more stable than the former for all BOX/DTE combinations. In addition, when the DTE is open, the two thienyl units can fold to form parallel conformers, by opposition to the antiparallel or unfolded conformers. Usually parallel conformers present a higher energy than the antiparallel ones, but in the case of compound 2 having a bulky substituent (R = pPh-SMe) on the terminal thienyl group, the enthalpy of one conformer is very close (1-2 kJ mol(-1)) to that of the most stable antiparallel one, making photocyclization less efficient. These conformational differences and the presence of parallel DTE forms have been substantiated by analyzing experimental H-1 NMR chemical shifts in light of their calculated values. These H-1 NMR chemical shift calculations led to the following statements: (i) Going from state I (DTE open, BOX closed) to state II (both DTE and BOX are open) the H-8 proton of compound 1 (R = Me) is deshielded by similar to 0.15 ppm. (ii) The deshielding of H-8 proton of compound 2 is larger and attains 0.41 ppm whereas H-7 is more shielded by 0.11 ppm. (iii) Then, going from compound 1 to compound 2 leads to deshielding of both H-7 and H-8 protons. As a consequence, the difference of photochromism gating efficiency among compounds 1, 2, and 3 (R = pPh-OMe) can be attributed to the stabilization of parallel conformer due to an establishment of an intramolecular interaction with BOX opening.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 84793-24-8 help many people in the next few years. Quality Control of Ethyl (S)-2-[(S)-4-Methyl-2,5-dioxo-3-oxazolidinyl]-4-phenylbutanoate.

Thermosensitive Behavior of Poly(ethylene Glycol)-Based Block Copolymer (PEG-b-PADMO) Controlled via Self-Assembled Microstructure

Stimuli-responsive, well-defined diblock copolymers (PEG-b-PADMO) comprising poly(ethylene glycol) (PEG, DP (degree of polymerization) = 45) as the hydrophilic and temperature-sensitive part and poly(N-acryloyl-2,2-dimethyl-1,3-oxazolidine) (PADMO, DP = 18-47) as the hydrophobic and acid-labile part self-assembled in water into spherical micelles with high aggregation number. The micellar structures and thermally induced phase transitions of the copolymers were investigated with (1)H NMR spectroscopy, light scattering, microscopy, turbidimetry, and fluorescence techniques. Thermoresponsive phase transitions of the copolymers in water were controlled via formation of core shell-type micelles with densely compact PEG corona. Their lower critical solution temperatures (LCSTs) were modulated within the range 40-72 degrees C by varying PADMO block length. This unusually low LCST was attributed to the densely packed PEG structure in the polymer micelles, which resulted in strong n-clustering attractive interactions and insufficient hydration of PEG chains in the shell and greatly enhanced the thermosensitivity. The LCST behavior can also be modulated by partial acid hydrolysis of PADMO segments through the resulting change of hydrophobicity.

Chiral Oxazolidine Complexes Derived from Phenolic Schiff Bases

Schiff bases derived from pyridyl- or salicyl-aldehydes and aminoalcohols can evolve to heterocyclic oxazolidines, which in the presence of cations allow the formation of uncommon coordination compounds. In this work, we report new Ni-II and mixed valence Mn-II/Mn-IV complexes derived from pyridyl oxazolidines and the unprecedented characterization of enantiomerically pure oxazolidines derived from the condensation of o-vanillin with phenylglycinol in the presence of NiII cations. The different reactivity of the pyridinic or phenolic Schiff bases has been compared, and the new systems have been structurally, optically, and magnetically characterized.

Synthesis of new ceramide analogues with allene in the sphingoid backbone

Ceramide is an important sphingolipid which can mediate a diverse range of biological activities. New ceramide analogues with an allene group in the sphingoid backbone were synthesized. The synthesis of the key intermediates involved the LiAlH(4)reduction of oxazolidine intermediates via a directed reduction-elimination reaction. Hydrolysis of the oxazolidine, liberation of the amino group, andN-acylation provided new ceramide analogues. These new analogues may provide new resources to study their bioactivities and the structure-activity relationship.
