Crystal structure of 6-de­oxy-α-l-psico­furan­ose

The title compound, C(6)H(12)O(5), was crystallized from an aqueous solution of 6-de­oxy-l-psicose (6-de­oxy-l-allulose, (3S,4S,5S)-1,3,4,5-tetra­hydroxy­hexan-2-one), and the mol­ecule was confirmed as α-furan­ose with a (3) T (4) (or E (4)) conformation, which is a predominant tautomer in solution...

Sumario:The title compound, C(6)H(12)O(5), was crystallized from an aqueous solution of 6-de­oxy-l-psicose (6-de­oxy-l-allulose, (3S,4S,5S)-1,3,4,5-tetra­hydroxy­hexan-2-one), and the mol­ecule was confirmed as α-furan­ose with a (3) T (4) (or E (4)) conformation, which is a predominant tautomer in solution. This five-membered furan­ose ring structure is the second example in the field of the 6-de­oxy-ketohexose family. The cell volume of the title compound [742.67 (7) Å(3), Z = 4 at room temperature] is only 1.4% smaller than that of β-d-psico­pyran­ose, C(6)H(12)O(6) (753.056 Å(3), Z = 4 at room temperature).
