article description
Crystals of the title compound, C(22)H(29)NO(5)·C(4)H(8)O(2), {[systematic name: (2R,3R,5R,5aS,6R,8aR,9S)-(5Z)-5-[3-butyl-tetra-hydro-6-methyl-2,5-methano-4,3,8a-[1]propan-yl[3]yl-idene-furo[3,2-f][1,4]oxazepin-7(5H)-yl-idene]-4-meth-oxy-3-methyl-furan-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. Inter-molecular contacts are observed between some C-bonded H atoms and nearby O atoms, perhaps indicating weak inter-actions which could influence the packing of species within the unit cell.
