L-Fructose was prepared in five steps from L-sorbose (1). 1,2-O-Isopropylidene-cr-L-sorbopyranose (2), prepared from 1, was selectively tosylated using phase transfer catalysis to give 1,2-O-isopropylidene-3-O-(p-tolylsulfonyl)-a-L-sorbopyranose (3). Formation of a 3,4-anhydro ring, followed by its
