Article abstract of DOI:10.1039/c39830000829

A synthesis of two diprotected (4S,6S)-4-hydroxy-6-hydroxymethyltetrahydropyran-2-ones has been developed from laevoglucosan; reaction of these lactones with a substituted lithium acetylide derivative followed by hydrogenation and acid catalysed cyclisati
