Ether derivatives are versatile organic compounds and have been applied in various fields of academia the chemical industry. Therefore, it is highly desirable to create procedures for their manufacture that more efficient sustainable. Catalytic reductive etherification with carbonyl moiety such as ketones/ aldehydes carboxylic acid has recently recognized a possible tool among several technique...

Living cationic polymerization is known for a good control over chain growth yielding polymers with well-defined molar mass distributions and low dispersities. However, the practical challenges involved in synthesis of poly(vinyl ether)s limited suitable post-polymerization modifications (PPM) via chemoselective click reactions. Herein successful controlled vinyl ethers bearing pendant CC doub...

Long-chain bases (LCBs) are the precursors to ceramide and sphingolipids in eukaryotic cells. They are formed by the action of serine palmitoyl-CoA transferase (SPT), a complex of integral membrane proteins located in the endoplasmic reticulum. SPT activity is negatively regulated by Orm proteins to prevent the toxic overaccumulation of LCBs. Here we show that overaccumulation of LCBs in yeast ...

We report a catalytic asymmetric total synthesis of the ascidian natural product perophoramidine. The synthesis employs a molybdenum-catalyzed asymmetric allylic alkylation of an oxindole nucleophile and a monosubstituted allylic electrophile as a key asymmetric step. The enantioenriched oxindole product from this transformation contains vicinal quaternary and tertiary stereocenters, and is obt...

Poly (vinyl ethers) are compounds with great value in the coating industry due to exhibiting properties such as high viscosity, soft adhesiveness, resistance saponification and solubility water organic solvents. However, main challenge this field is synthesis of vinyl ether monomers that can be synthetized by methodologies transfer, reduction phosphate ether, isomerization, hydrogenation acetyl...

In this study, a feasible green method for the synthesis of copper oxide nanocrystalline is described by using sour cherry juice which has a significant effect on crystalline size, and morphology. The benefits of the green method, not only nanometer scale are formed but also low-cost method are obtained in a normal atmosphere which it has been used (CH3COO)2Cu.H2O individually as Cu sources. Al...
