(+)-14bα-3-Oxoglycyrrhetinic acid: catemeric hydrogen bonding in a non-racemic triterpenoid diketo acid

H. W. Thompson, R. A. Lalancette and E. M. Kikolski

The title compound, (+)-10,13-dioxo-2α,4aβ,6aα,6bβ,9,9,12aβ-heptamethyl-1,2,3,4,4a,5,6,6a,6b,7,8,8aα,9,10,11,12,12a,12bα,13,14bα-eicosahydropicene-2β-carboxylic acid, C₃₀H₄₄O₄, aggregates as carboxyl-to-ketone hydrogen-bonding catemers. Hydrogen bonds progress from the carboxyl group of one molecule to the remote-ring ketone group of a translationally related neighbor in an adjoining cell connected by a common a cell-edge [O

O = 2.766 (3) Å and O—H

O = 163°], yielding chains that extend in the [011] direction. In the crystal structure, there are also four C—H

O close contacts.

Alert level A
PLAT029_ALERT_3_A _diffrn_measured_fraction_theta_full Low .......       0.91

Author Response: _diffrn_measured_fraction_theta_full Low .......0.91. (Alert level A). Even though we collected data out to 0.83 \%A, the crystal diffracted poorly beyond 0.88 \%A resolution, where more than 40% of the missing data lie. Larger crystals were not obtainable, and since the crystals of this compound are no longer available, we can only rely on the current data set.

Experimental. 'crystal mounted on cryoloop using Paratone-N'

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.
