Correction for 'Unsymmetrical 1,1-diborated multisubstituted sp(3)-carbons formed via a metal-free concerted-asynchronous mechanism' by Ana B. Cuenca et al., Org. Biomol. Chem., 2015, 13, 9659-9664.

Unsymmetrical dendrimers, containing both mannose binding units and coumarin fluorescent units, have been prepared using click chemistry and shown to be highly efficient, dual-purpose recognition/detection agents for the inhibition of hemagglutination.

Copper-catalyzed direct olefination of benzaldehydes into 1,3-diarylpropenes by a novel domino Knoevenagel-decarboxylation-Csp(3)-H activation sequence is reported. This method provides a concise and effective route toward the synthesis of unsymmetrical 1,3-diarylpropene derivatives.

A new direct conversion of O,O-acetals to esters via O,P-acetal intermediates was developed. The regioselective cleavage of unsymmetrical cyclic acetals occurred to give the more crowded esters as single isomers.

A highly efficient and mild palladium-catalyzed decarboxylative cross-coupling of aryl boronic acids and alkynyl carboxylic acids for the synthesis of unsymmetrical substituted alkynes is described for the first time.

Imidazolium salts were conveniently prepared by direct aryl quaternization using arylboronic acids. This process features the tolerance of a broad range of functional groups and excellent chemoselectivity, and is especially effective for the synthesis of unsymmetrical imidazolium salts.

In the title compound, C(13)H(16)N(4)O(2), the central tetra-zine ring adopts an unsymmetrical boat conformation with the two C atoms as flagpoles. This compound can be considered as having homoaromaticity.

An efficient and general method for the synthesis of unsymmetrical tetrasubstituted ureas from carbamoylimidazole is described. The conversion is achieved by the concurrent quarternization of the imidazole nitrogen and activation of amines with AlMe(3).

nickel (ii) and copper (ii) complexes of highly unsymmetrical tetradentate schiff base have been synthesized by the template reaction of half-units n-(1-hydroxy-2-acetonaphtone)-1-amino-2-phenyleneimine (hl) and n-(2-hydroxyacetophenone)-1-amino-2-phenyleneimine (hl1) with the glyoxalphenylhydrazone. the complexes have been characterized by elemental analyses, conductance, ir, 1h nmr and uv spe...
