Copper-mediated anomeric: O -arylation with organoboron reagents

Copper-mediated couplings of arylboroxines with glycosyl hemiacetals furnish O-aryl glycosides via Csp2-O bond formation. The method enables the anomeric O-arylation of protected pyranose and furanose derivatives, and is tolerant of functionalized arylboroxine partners. Whereas mixtures of anomers are formed from glucopyranose, galactopyranose and arabinofuranose hemiacetals, the α-anomer is generated selectively from mannopyranose and mannofuranose-derived substrates.

Copper-Catalyzed Cyanation of Aryl- and Alkenylboronic Reagents with Cyanogen Iodide

Direct catalytic cyanation of organoboronic acids with cyanogen iodide has been achieved by using a copper-bipyridine catalyst system. The cyanation reaction is likely to occur through two catalytic cycles: copper(II)-catalyzed iodination of organoboronic acids and the following cyanidocopper(I)-mediated cyanation of organic iodides.

Formation of hetero-boroxines: Dynamic combinatorial libraries generated through trimerization of pairs of arylboronic acids

Condensation of pairs of arylboronic acids provided homo- and hetero-boroxines in solution as evidenced from NMR spectra, and those boroxines were detected in the gas phase by GC-MS spectrometry. Equilibrium constants for the formation of these boroxines in solution were obtained through integration of pertinent signals in the NMR spectra of the mixtures ofboronic acids.
