The title compound, C<sub>12</sub>H<sub>21</sub>NO<sub>7</sub>, (<b>I</b>), is conformationally unstable; the predominant form present in its solution is the β-pyran-ose form (74.3%), followed by the β- and α-furan-oses (12.1 and 10.2%, respectively), α-pyran-ose (3.4%), and traces of the acyclic carbohydrate tautomer. In the crystalline state, the carbohydrate part of (<b>I</b>) adopts the <sup>2</sup> <i>C</i> <sub>5</sub> β-pyran-ose conformation, and the amino acid portion exists as a zwitte ...[more]
