STRUCTURAL CHANGES IN THE ACYLATION OF KETOSES. 1,2,3,4,5,6-HEXA-O-BENZOYL-L-xylo-HEX-1-ENITOL FROM L-SORBOSE

Gelpi, Maria E.,Teglia, Maria C.,Cadenas, Raul A.

, p. 73 - 78 (2007/10/02)

Benzoylaton of L-sorbose at room temperature with an excess of benzoyl chloride in pyridine gave a mixture of unsaturated cyclic and acyclic benzoates.The synthesis, and the structure of the title compound based on spectroscopic and ozonolysis studies, are reported.Ethyl 2,3,4,5-tetra-O-benzoyl-L-xylonate is also described, as well as the mass spectra of these acyclic benzoates.
