Three different fluoro- or chloro-substituted 1'-de­oxy-1'-phenyl-[beta]-D-ribo­furan­oses

J. W. Bats, A. Zivkovic, J. Parsch and J. W. Engels

Synopsis: The five-membered furan­ose ring of three fluoro- or chloro-substituted 1'-de­oxy-1'-phenyl-[beta]-D-ribo­furan­oses has a conformation between a C2'-endo,C3'-exo twist and a C2'-endo envelope. The ribo­furan­ose groups are connected by O-H...O hydrogen bonds to symmetry-related mol­ecules to form layers. The orientation of the benzene ring is independent of the substitution pattern of the ring and depends mainly on crystal-packing effects.

Formula: Two isomers of C11H11F3O4, and C11H13ClO4
