Cyclopentyl Methyl Ether: An Elective Ecofriendly Ethereal Solvent in Classical and Modern Organic Chemistry
TLDR
Cyclopentyl methyl ether's low toxicity, high boiling point, low melting point, hydrophobicity, chemical stability towards a wide range of conditions, exceptional stability towards the abstraction of hydrogen atoms, relatively low latent heat of vaporization, and the ease with which it can be recovered and recycled enable its successful employment as a solvent in a widerange of synthetic applications.
Straightforward access to 4-membered sulfurated heterocycles: introducing a strategy for the single and double functionalization of thietane 1-oxide.
TLDR
A strategy for the stereoselective functionalization of thietane 1-oxide has been developed using corresponding organometallic intermediates that reacted with electrophiles leaving intact the 4-membered ring.
Harnessing the ortho-directing ability of the azetidine ring for the regioselective and exhaustive functionalization of arenes.
TLDR
This work demonstrates how the directing ability of the azetidine ring could be useful for regioselective ortho-C-H functionalization of aryl compounds and n-hexyllithium emerged as a safer, yet still effective, basic reagent for the hydrogen/lithium permutation relative to the widely used reagent nBuLi.
V(IV)O versus V(IV) complex formation by tridentate (O, N(arom), O) ligands: prediction of geometry, EPR 51V hyperfine coupling constants, and UV-Vis spectra.
TLDR
EPR spectra of several non-oxido V(IV) species were compared using relevant geometrical parameters to demonstrate that in the case of tridentate ligands the (51)V hyperfine coupling constant is related to the geometric isomerism (meridional or facial) rather than the twist angle Φ, which measures the distortion of the hexacoordinated structure toward a trigonal prism.
Behavior of the potential antitumor V(IV)O complexes formed by flavonoid ligands. 2. Characterization of sulfonate derivatives of quercetin and morin, interaction with the bioligands of the plasma
TLDR
The biotransformation in the plasma and red blood cells of two potential antitumor V(IV)O complexes formed by flavonoid ligands and their sulfonic derivatives was studied by spectroscopic and computational methods.
Computational NMR as Useful Tool for Predicting Structure and Stereochemistry of Four‐Membered Sulfur Heterocycles
We report a computational NMR study of stereochemically challenging thietane 1-oxides. Comparison of calculated and experimental data allows to assign structure and stereochemistry to the examined
BH3-promoted stereoselective β-lithiation of N-alkyl-2-phenylaziridines.
BH(3) complexes of N-alkyl-2-phenylaziridines have been synthesized and their structure and stereochemistry proved with DFT calculations and NMR experiments. It has been demonstrated that the Lewis
Active-alkali metal promoted reductive desulfurization of dibenzothiophene and its hindered analogues
Dibenzothiophene and some related organosulfur compounds are efficiently reductively desulfurized under mild reaction conditions, with Na and/or Li metal in the presence of a catalytic amount of
Regio- and Stereoselective Synthesis of Sulfur-Bearing Four-Membered Heterocycles: Direct Access to 2,4-Disubstituted Thietane 1-Oxides.
TLDR
The results demonstrate that a stereoselective functionalization at the C2, C4 positions of a thietane is feasible, leaving intact the four-membered ring.
