Stemofoline ethyl acetate solvate

Abstract

Crystals of the title compound, C22H29NO5·C4H8O2, {[systematic name: (2R,3R,5R,5aS,6R,8aR,9S)-(5Z)-5-[3-butyl­tetra­hydro-6-methyl-2,5-methano-4,3,8a-[1]propan­yl[3]yl­idene­furo[3,2-f][1,4]oxazepin-7(5H)-yl­idene]-4-meth­oxy-3-methyl­furan-2(5H)-one ethyl acetate solvate} were isolated from the root extracts of Stemona aphylla (Stemonaceae). The structure closely resembles those of stemofoline derivatives which have previously been reported. Inter­molecular contacts are observed between some C-bonded H atoms and nearby O atoms, perhaps indicating weak inter­actions which could influence the packing of species within the unit cell.

Comment

The crystallographic asymmetric unit consists of one C22H29NO5 molecule and one ethyl acetate molecule of crystallization. Examination of distances and angles around the N atom shows N4—C5 to be slightly shorter than the other two distances and for C5—N4—C9a to be significantly larger than the other two angles. These features were also observed in the closely related compounds reported by Seger et al. (2004). Unfortunately, coordinates are not available for the structure of stemofoline hydrobromide hydrate (Irie et al., 1970).

Experimental

Stemofoline was isolated from the root extracts of Stemona aphylla (Stemonaceae) as reported earlier (Mungkornasawakul et al., 2009) and was crystallized from ethyl acetate/40–60°C petroleum ether. The sample had m.p. 71.5–73.2 °C (lit., Irie et al. (1970), 87–89 °C) and [α]D23 269.1 (c 0.18, CHCl3) (lit., Irie et al. (1970), [α]D 273 (MeOH)).

Refinement

The compound is enantiometrically pure but the anomolous dispersion terms are very low for all elements in the structure and so the absolute configuration can not be determined in this experiment. Consequently Friedel-pair reflections have been averaged and the Flack parameter has not been refined. The molecule is presented with the same absolute configuration as that determined by X-ray crystallography for a closely related compound (Seger et al., 2004). It is also consistent with that reported for stemofoline.HBr.H2O (Irie et al., 1970), though the absolute structure determination performed there could possibly be regarded as not totally reliable.

All hydrogen atoms were observed in difference electron density maps prior to their inclusion in the structure. They were included at calculated positions and then were initially refined with soft restraints on the bond lengths and angles to regularize their geometry (C—H in the range 0.93–0.98 Å) and with Uiso(H) in the range 1.2–1.5 times Ueq of the parent atom, after which the positions were refined with riding constraints.

One strong reflection with poor agreement between Fo and Fc was removed from the refinement as being unreliably measured.

The largest features in the final difference electron density map are located along C—C bonds.
