2-De-oxy-2,3-O-isopropyl-idene-2,4-di-C-methyl-?-l-arabinose.


ABSTRACT: X-ray crystallography unequivocally confirmed the stereochemistry of the C atom at position 2 in the carbon scaffold of the title mol-ecule, C(10)H(18)O(4). The pyran-ose ring exists in a chair conformation with the methyl group on the C atom in the 2 position in an equatorial configuration. The absolute stereochemistry was determined from the starting material. The crystal structure consists of O-H?O hydrogen-bonded chains of mol-ecules running parallel to the b axis.
