Brønsted acid-catalyzed stereoselective allylation of exo-glycals with allyltrimethylsilane
… and to date, many studies have failed to exploit exo-glycals as starting materials. The allylation methodologies of sugar lactol and sugar lactone starting materials suffer from poor regio- and stereoselectivity. Recently, we have developed a synthetic method for the allylation of exo-glycals …

Synthetic methodologies toward the functionalization of benzhydrols and carbohydrates
… reaction conditions for the conversion of exo-glycals to tertiary glycosyl azides have been developed. The glycosylation reactions proceeded at room temperature with short reaction times and afforded the targeted products in high yields with virtually exclusive diastereoselectivity to the …

Synthesis and transformations of 2-thiocarbohydrates
… (CAN) mediated thiocyanate radical additions to glycals In this dissertation, a facile entry was developed for the synthesis of 2-thiocarbohydrates and their transformations. Initially, CAN mediated thiocyanation of carbohydrates was carried out to obtain the basic building blocks …
