The configuration of the anomeric glycosidic linkages is crucial for maintaining the biological functions and activities of carbohydrate molecules. However, their stereochemistry control in glycosylation represents one of the most challenging tasks in car
Knoevenagel Condensation of Phosphinoylacetic Acids with Aldehydes: An Efficient One-Pot Strategy for the Synthesis of P-Functionalized Alkenyl Compounds

A wide range of commercially available aldehydes have been applied to Knoevenagel condensation reaction to give E -alkenylphosphine oxides and vinylphosphine oxides. The readily available phosphinoylacetic acids derived from P(O)-H compounds were used as the starting materials in the reaction, providing a highly stereoselective and efficient method for constructing α,β-unsaturated phosphine oxides. Moreover, this simple and practical procedure provides an alternative and more environmentally friendly synthesis strategy for this type of P-functionalized alkenyl compounds.

Several methods for rapid sequestration, fluorometric detection, and the subsequent mass spectroscopic analysis of lanthanide ions using surface modified polystyrene magnetic microspheres are demonstrated. Mixed-ligand antenna complexes of Eu3+ in which one of the ligands is attached to the surface of the microspheres have been used as a means for the sequestration, immobilization, and detection of these ions. Using the ion-exchange properties of these microspheres, this scheme has been extended to the detection of nonluminescent ions. The principles of these assays form the basis for operation of a portable microfluidic device for general analytical and nuclear forensics applications and indicate the manner in which the established methods of analytical chemistry, such as liquid-liquid extraction and ion-exchange chromatography, can be adapted for such miniature devices.
Complex formation of some carbamoylmethylphosphine oxides and methylenediphosphine dioxides with alkali metal cations. The "anomalous aryl enhancement" effect

Conductometry in anhydrous hexane at 25°C was used to measure the stability constants of alkali cation complexes of a series of N,N-diethylcarbamoylmethylphosphine oxides and methylenediphosphine dioxides. The "anomalous aryl enhancement" effect is the strongest in the complexes with tetraphenyldiphosphine dioxide.

Various calix[4]arene tetraalkyl ethers and a calix[5]arene pentaalkyl ether substituted at the upper rim by the CMPO-like functional group -NH-C(O)-CH2-P(O)Ph2 as well as some linear model compounds have been synthesized for the fir
ALKYLATION REACTIONS OF DIALKYL HYDROGEN PHOSPHITES AND DIARYLPHOSPHINE OXIDES UNDER PHASE-TRANSFER CONDITIONS
Petrov, K. A.,Sivova, L. I.,Smirnov, I. V.,Kryukova, L. Yu.
, p. 264 - 268 (2007/10/02)
It was shown that phosphonates and tertiary phosphine oxides can be synthesized by the alkylation of acid phosphites and diarylphosphine oxides in a nonpolar solvent in presence of solid potassium hydroxide and potassium carbonate and also catalytic amounts of 18-crown ether (or in its absence). (Diarylphosphinyl)methyl ethers of mono- and oligo-etylene glycols were synthesized by the reactions of diaryl(chloromethyl)phosphine oxides with lithium glycolates
A Simple Synthesis and Some Synthetic Applications of Substituted Phosphide and Phosphinite Anions
Tsvetkov, E. N.,Bondarenko, N. A.,Malakhova, I. G.,Kabachnik, M. I.
, p. 198 - 208 (2007/10/02)
Based on data for the acidity relationship of phosphines and phosphinous acids and water in dimethyl sulfoxide and water, a simple method is reported for the generation of phosphide and phosphinite anions by the action of concentrated aqueous alkali on primary and secondary phosphines as well as phosphinous acids in dimethyl sulfoxide or other dipolar aprotic solvents.Alkylation of the anion yields secondary and tertiary phosphines, polyphosphines, functionally substituted phosphines as well as similarly substituted phosphine oxides.Phosphinous acids have beenalkylated in various solvents in two-phase systems containing concentrated aqueous alkali and tetrabutylammonium iodide as phase transfer catalyst.
