Concise and efficient synthesis of bioactive natural products pegamine, deoxyvasicinone, and (-)-vasicinone

Vinyl sulfone-modified carbohydrates: an inconspicuous group of chiral building blocks

A reagent system comprising tetrabutylammonium nitrate–trifluoroacetic anhydride–triethylamine has been developed for the synthesis of 2-nitroglycals from various protected glycals. The base-catalyzed Ferrier rearrangement on tri-O-acetylated 2-nitroglycals has been reported for the first time. Reactivity of these nitroacetates and associated selectivity has been examined, and some of the products have been converted into 2,3-diamino-2,3-dideoxyglycosides and methyl N-acetyl-d-lividosaminide.
