The title 1,Zanhydro sugar (8) was synthesized from D-xylose. The key intermediate for the synthesis was 2-0-acetyl-3,4-di-0-benzyl-@-o-xylopyranosyl fluoride, which was transformed into crystalline 8 by ring closure with potassium tert-butoxide. Comparison of the observed vicinal coupling constants
