One pot conversion of ketoses into sugar β-peptides via a ritter reaction
Schweizer,Lohse,Otter,Hindsgaul
, p. 1434 - 1436 (2001)
α-D-Galacto-2-deoxy-oct-3-ulopyranosonic acids can be converted into unnatural glycopeptides via a one pot intramolecular Ritter reaction. Initially, the ketopyranoside reacts under Lewis acid catalyzed conditions with a nitrile (aromatic or aliphatic) to
