L-Lemonose, the glycosidic part of (–)-lemonomycin, has been synthesized in ten steps with 18% overall yield from Dthreonine. The key steps are a double, highly diastereoselective Grignard addition to a Weinreb amide and a chemoselective oxidation of a pri ...
Various methods for the synthesis of bimetallic complexes, in which two different metal fragments which are connected by two or three halogeno bridges, are reported. The reactions are usually fast and give rise to structurally defined products in quantitat ...
The influence of conditions of heat treatment of a solution [Zn(H2O)(O2C5H7)(2)] in 1-butanol (temperature 125-185 degrees C, treatment times 2, 4, and 6 h) on dispersion and microstructure of the formed nanocrystalline and poorly aggregated zinc oxide, pr ...
A new, simple, and efficient procedure for the one-pot Ugi four-component reaction of alcohols instead of aldehydes is described. Using a stoichiometric amount of IBX or only 1-2% of sodium 2-iodobenzenesulfonate in the presence of Oxone, a wide range of p ...
FAIMS's ion separation mechanism is based on analyte's characteristic nonlinear relationship between its ion mobility and applied electric field strength. Present characterization methods for this nonlinear relationship are based on precarious assumptions ...
Alkynes and nitriles are valuable building blocks in organic synthesis and also have multiple applications in chemical biology and materials science. Due to the high availability of tertiary alcohols, developing methods for their conversion into alkynes an ...
A Pd-catalyzed method based on the use of a molecular tether is described for olefin difunctionalization. Enabled by an easily introduced trifluoroacetaldehyde-derived tether, a simultaneous introduction of oxygen and nitrogen heteroatoms across unsaturate ...
Biofuels are considered sustainable and renewable alternatives to conventional fossil fuels. Biobutanol has recently emerged as an attractive option compared to bioethanol and biodiesel, but a significant challenge in its production lies in the separation ...
Electrochemical reduction of carbon dioxide, using the electricity generated from renewable energy sources, has the potential of rendering a carbon-neutral energy economy. Developing selective, efficient and robust electrocatalysts is the key step towards ...
The condensational growth of a water droplet follows water vapor accommodation and is described by the mass accommodation coefficient, a. To determine a for droplets coated by straight chain and branched alcohols, we perform molecular dynamics simulations ...
