Iodine as a reagent for the ready hydrolysis of prop-1-enyl glycosides, or their conversion into oxazolines

Abstract
Iodine in oxolan with sutiable additives rapidly effects the hydrolysis of prop-1-enyl glycosides to free sugars, and the cyclization of prop-1-enyl β-glycosides of N-acylglucosamines to oxazolines.
