Abstract
Acetylation of 1,5-anhydro-D-fructose under acidic conditions gave
two crystalline acetylated dimeric forms, which by X-ray analysis
were shown to be diastereomeric spiroketals formed between C-2 and
C-2´/C-3´. The structures of the compounds differed only at the
configuration at C-2. Acetylation or benzoylation of
1,5-anhydro-D-fructose in pyridine yielded
3,6-di-O-acetyl-1,5-anhydro-4-deoxy-D-glycero-hex-3-enos-2-ulopyra
-nose or crystalline
1,5-anhydro-3,6-di-O-benzoyl-4-deoxy-D-glycero-hex-3-enos-2-ulo-py
ranose.
