Abstract
In the title molecule, C28H44O, the two six-membered rings have a chair conformation and the two five-membered rings haveenvelope conformations. The crystal packing exhibits no short intermolecular contacts. The absolute configuration was assigned to correspond with that of the known chiral centres in a precursor molecule, which remained unchanged during the synthesis of the title compound.

Comment
Many analogues of brassinolide as plant regulator have been isolated from a wide variety of plants, and there has been intense activity in synthesis of these brassinosteroids. We found the same phenomena that our immediates and products were synthesized with impurities by McMorris and Brosa's methods. Herewith we present the crystal structure of the title compound, (I).
In the title molecule, ring A shows an envelope conformation, and atoms C2, C3, C5 and C10 are coplanar with the r.m.s. deviation of 0.018 (1) Å. Atom C1 deviates 0.446 (3) Å from this mean plane, which make a dihedral angle of 68.20 (13) ° with the plane C3/C4/C5. Rings B and C have regular chair conformations, respectively; while ring D has an envelope conformation.
Experimental
(22E,24R)-3α,5-Cyclo-5α-ergosta-22-en-6-one was synthesized according to the known method (McMorris et al., 1993) as a powder. Crystals of (I) suitable for structure analysis were obtained by slow evaporation from a mixture of EtOAC and ethanol (volume proportion, 9:1) as colourless prisms.
Refinement
C-bound H atoms were placed at calculated positions (C—H 0.93–0.98 Å) and constrained to ride on their parent atoms, withUiso(Hmethyl) = 1.5Ueq(Cmethyl) or Uiso(Hnon-methyl) = 1.2Ueq(Cnon-methyl). Because of negligible anomalous scattering effects, 2359 Friedel pairs were averaged in the refinement. The absolute configuration has been assigned to correspond to the known chiral centres in a precursor molecule, which remained unchanged during the synthesis of (I).

Special details
| 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 > σ(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. |
