Chiral Induction in Cycloaddition Reactions of Azomethine Ylides to Synthesis of New Enantiomerically Pure Spiro Oxindolopyrrolizidines
An efficient one-pot three-component procedure for the synthesis of new chiral spiro-oxindolopyrrolizidines with highly regio-, diastereo-, and enantioselective from 1,3-dipolar cycloaddition of azomethine ylides and optically pure active cinamoyl oxazolidinone are described. The process occurs at room temperature in aqueous ethanol as green solvent and in the absence of any bidentate chelating...

متن کاملSelectivity of competitive multivalent interactions at interfaces.
The development of synthetic, low-molecular-weight ligand receptor systems for the selective control of biomolecular interactions remains a major challenge. Binding of oligohistidine peptides to chelators containing Ni2+-loaded nitrilotriacetic acid (NTA) moieties is one of the most widely used and best-characterised recognition systems. Recognition units containing multiple NTA moieties (multi...
متن کاملReactions at interfaces as a source of sulfate formation in sea-salt particles.
Understanding the formation of sulfate particles in the troposphere is critical because of their health effects and their direct and indirect effects on radiative forcing, and hence on climate. Laboratory studies of the chemical and physical changes in sodium chloride, the major component of sea-salt particles, show that sodium hydroxide is generated upon reaction of deliquesced sodium chloride...
متن کاملComment on "Reactions at interfaces as a source of sulfate formation in sea-salt particles" (II).
Interfaces As a Source of Sulfate Formation in Sea-Salt Particles” (II) In the laboratory, Laskin et al. (1) studied the role of the surface reaction OH Cl 3 OH Cl for influencing the pH and oxidation of S(IV) in the marine boundary layer. They concluded that it increases the sulfate production rate in tropospheric sea-salt particles. However, in their extrapolation to atmospheric conditions th...
