Stereoselective template-directed C-glycosidation. Silver(I)-mediated intramolecular reactions of (2-pyridylthio)glycosidic silyl enol ethers

Article abstract of DOI:10.1016/S0040-4039(00)92337-2

The synthesis and highly stereoselective intramolecular cyclization reactions of a series of (2-pyridylthio)glycosides possessing silyl enol ether-containing appended groups are described. The cyclizations are explained in terms of S(N)1-like reactions proceeding via anomeric cationic species.
