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

Add time:08/15/2019    Source:sciencedirect.com

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 SN1-like reactions proceeding via anomeric cationic species.
