Efficient Synthesis of Glycosyl Enaminoesters Directly from Glycosyl Azides

A convenient methodology has been developed for the synthesis of glycosylenaminoesters directly from glycosyl azides under hydrogenetion condition. Yields were moderate to good in all cases.

Mild and efficient hydrolysis of thioglycosides to glycosyl hemiacetals using N-iodosaccharin

A convenient methodology has been developed for the mild hydrolysis of thioglycosides to the corresponding hemiacetals using N-iodosaccharin without any requirement of co-activator. Most of the functional groups used for the protecting group manipulation of carbohydrates are remain unaffected under the reaction condition.
