Gold(III)-Catalyzed Glycosylation using Phenylpropiolate Glycosides: Phenylpropiolic Acid, An Easily Separable and Reusable Leaving Group
An efficient and operationally simple gold(III)-catalyzed glycosylation protocol was developed using newly synthesized benchtop stable phenylpropiolate glycosyl (PPG) donors. Gold(III)-catalyzed activation of PPGs proceeds well with various carbohydrate a
Synthesis of the hyper-branched core tetrasaccharide motif of chloroviruses
Chemical synthesis of complex oligosaccharides, especially those possessing hyper-branched structures with one or multiple 1,2-cisglycosidic bonds, is a challenging task. Complementary reactivity of glycosyl donors and acceptors and proper tuning of the s
An unusual synthesis of 2-pyridone and 3,5-dihydroxypyridine from a carbohydrate
An unusual aromatization to perbenzylated 3,5-dihydroxy-6-(hydroxymethyl)- 2-pyridone was demonstrated utilizing sugar lactam, under strong basic conditions, derived from d-Galactose. 2-Pyridone was efficiently converted into a pharmaceutically relevant s
