In the title compound, C38H29N7O12, the five-membered ring adopts an in which the `flap' is cis to the cyclopropane group. This conformation is similar to those of other bicyclo[3.1.0]hexane analogues for which crystal structures have been reported. The of the stereogenic centers on the cyclopentane ring, as determined by comparison with the known configurations of the stereogenic centers in the (2S)-2-acetoxy-2-phenylacetoxy groups, is 1(R), 2(R), 3(R), 4(R) and 5(S). An intramolecular N—H⋯O hydrogen bond is present.

Compound (II) (5.8 mg, 0.011 mmol) was dissolved in CH3OH (1 ml) and 1M 2,4-dinitrophenylhydrizine (1 ml) was added. The mixture was swirled for 1 min and then the solution was concentrated. The resulting residue was purified by
(3:1 hexane-EtOAc) to give (III) (yield 4.2 mg, 53%) as a yellow solid. This material was recrystallized from CH3OH to give a crystalline material (m.p. = 331–333 K).Hydrogen atoms were generated in idealized positions (according to the sp2 or sp3 geometries of their parent carbon or nitrogen atoms), and then refined using a riding model with fixed C—H (0.95–1.00 Å) and N—H (0.88 Å) and with Uiso(H) = 120% of the Ueq for the parent atoms.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

As part of an ongoing program on the synthesis of furanose ring mimetics (Callam & Lowary, 2000; Callam & Lowary, 2001; Callam et al., 2001; Centrone & Lowary, 2002), we have endeavored to prepare compounds of the general structure (I). The route we developed for the preparation of these materials (Li & Lowary, 2008) started from an achiral starting material and relied upon a late stage resolution by derivatization with O-acetyl-(S)-mandelic acid. In the course of synthesizing (I), aldehyde (II) was prepared and, to determine the absolute configuration of the sterogenic centers in the cyclopentane ring, it was reacted with 2,4-dinitrophenylhydrazine to afford hydrazone derivative (III), which is a crystalline solid.

The structure of (III) in the crystal is shown in Fig. 1. The five-membered ring adopts an envelope conformation in which C3 is displaced below the plane formed by C1, C2, C4 and C5 and is therefore oriented cis to the fused cyclopropane moiety. Thus, the conformation of this ring is similar to that in other bicyclo[3.1.0]hexane analogues (examples: Gurskaya et al., 1990; Gurskaya et al., 1996; Gallucci et al., 2000; Garcia et al., 1992; Guthrie et al., 1981; Màrton-Merész, et al., 1983; Biswas et al., 1996; Bai et al., 2004). The absolute configuration of the stereogenic centers in the molecule could be established by comparison with those present in the (S)—O-acetylmandeloxyl substituents attached at C2 and C3. Thus, the absolute configuration was established as 1(R), 2(R), 3(R), 4(R), 5(S).
