Ethoxycarbonylmethylenetriphenylphosphorane in carbohydrate chemistry : an easy access to functionalised 2-deoxy-3,6-anhydrohexono-1,4-lactones
摘要:
2-Deoxy-3,6-anhydrohexono-1,4-lactones are obtained efficiently from aldehydosugars in a two-step sequence involving a Wittig followed by acid-catalysed methanolysis.
