[GRAPHICS]This letter describes a single flask strategy to the synthesis of a alpha-C-glycosides from glycals. This protocol couples a glycal epoxidation reaction with a C-2 alkoxy-directed carbon-carbon bond forming reaction.
α-Heteroarylation of Ketones <i>via</i> the Umpolung Reaction of <i>N</i>-Alkoxyenamine
A new method has been developed for the umpolung α-heteroarylation of ketones via an N-alkoxyenamine. The treatment of ketones with tris(heteroaryl)aluminum reagents in the presence of isoxazolidine gave the corresponding α-heteroarylated ketones in moderate to good yields.

In the presence of pinacolone, the in situ prepared triorganoaluminium reagents reacted with aromatic aldehydes to give ketones in moderate to high yield. We propose that the products are formed via a tandem organoaluminium reagents addition–Oppenauer oxidation sequence.
