Trichloro-oxazolines as Activated Donors for Aminosugar Coupling
Donohoe, Timothy J.,Logan, James G.,Laffan, David D. P.
, p. 4995 - 4998 (2003)
(Equation presented) Starting from tri-O-acetyl-o-glucal, a combination of the Overman rearrangement and subsequent dihydroxylation produces a range of aminosugars. These can be activated by formation of the corresponding trichloro-oxazolines, which are e
