Crystal structure of 3-C-(N-benzyl-oxy-carbon-yl)amino-methyl-3-de-oxy-1,2:5,6-di-O-iso-propyl-idene-?-d-allo-furan-ose.


ABSTRACT: The title compound, C21H29NO7 (1) [systematic name: benzyl ({(3aR,5S,6R,6aR)-5-[(R)-2,2-dimethyl-1,3-dioxolan-4-yl]-2,2-di-methyl-tetrahydro-furo[2,3-d][1,3]dioxol-6-yl}meth-yl)carbamate], consists of a substituted 2,2-di-methyl-tetra-hydro-furo[2,3-d][1,3]dioxolane skeleton. The furan-ose ring adopts an envelope conformation close to C 3-exo, where the C atom substituted by the benzyl carbamate group is the flap. The fused dioxolane ring also adopts an envelope conformation, as does the terminal dioxolane ring, with in each case an O atom as the flap. In the crystal, mol-ecules are linked by N-H?O and C-H?O hydrogen bonds, forming chains propagating along the b-axis direction.
