Abstract (sommario):
Enantiomerically enriched diaryl, aryl heteroaryl, and dihetero­aryl alcohols are an important family of compounds known for their biological properties. Moreover, these molecules are highly privileged scaffolds used as building blocks for the synthesis of pharmaceutically relevant products. This short review provides background on the enantioselective arylation and heteroarylation of carbonyl compounds, as well as, the most significant improvements in this field with special emphasis on the application of organometallic reagents.1 Introduction2 Background on the Enantioselective Synthesis of

Abstract (sommario):
A critical test of additivity for partial molar volume has been made at 25 °C in CCl4 with polyethylene glycol dimethyl ethers, crown ethers, cycloalkanes, n-alkanes, and others. Plots of partial molar volume at infinite dilution [Formula: see text] against the properly chosen number of repeating unit (n) are linear except for small cyclic molecules, and the slopes of homologous straight chain and ring compounds are the same. The values of [Formula: see text] extrapolated to n = 0 for cycloalkanes and crown ethers support the validity of the contribution due to the translational kinetic energy

Abstract (sommario):
The synthesis of two new series of polyoxygenated macrocyclic derivatives, 1 and 2, was realised. All these compounds have a 1,4-benzodioxinic moiety and are related to crown ethers, benzocrown ethers, and lariat ethers. The complexing properties of sodium and potassium ions were studied using potentiometry in methanol; results thus obtained are compared to data, previously reported in the literature, for classical polyoxygenated macrocyclic compounds. Keywords: polyoxygenated macrocycles, 1,4-benzodioxin, lariat ethers, sodium and potassium complexes, solvent methanol.

Abstract (sommario):
Mild methods to cleave the carbon-oxygen (C−O) bond in alkyl ethers could simplify chemical syntheses through the elaboration of these robust, readily available precursors. Here we report that dibromoboranes react with alkyl ethers in the presence of a nickel catalyst and zinc reductant to insert boron into the C−O bond. Subsequent reactivity can effect oxygen-to-nitrogen substitution or one-carbon homologation of cyclic ethers and more broadly streamline preparation of bioactive compounds. Mechanistic studies reveal a cleavage-then-rebound pathway via zinc/nickel tandem catalysis.
