A Versatile and Stereocontrolled Route to Pyranose and Furanose C-Glycosides.
The novel precursors (I) and (III) are successfully transformed to the α-C- and
47- 177 —
β-furanosides (II) and (IV), respectively. α-C-pyranoside (V) is prepared in a stereocontrolled fashion from (I) and (III). The β-C-pyranoside (VI) is isolated by crystallization from a mixture containing (V). The possibility of further functionalization at the
ring and/or aglycon positions of the products is demonstrated. — (HARVEY*, J. E.;
