Stereoselective α-Glycosylation of Nitro Sugar Evernitrose: Synthesis of the Terminal AB Unit of Everninomicin Antibiotics

Article abstract of DOI:10.1021/jo00025a034

The stereoselective α-glycosylation of branched-chain nitro sugar evernitrose (17, 2,3,6-trideoxy-3-C-methyl-4-O-methyl-3-nitro-α-L-arabino-hexopyranose) is described. 1-O-p-Nitrobenzoyl derivatives 18β and 18α were prepared as glycosyl donors starting fr
