Abstract: | The solid-state structure of the title enaminone, C15H17N1O7, the C adduct obtained from the reaction of 4-aminopent-3-en- 2-one with methoxymethylene Meldrum's acid, has been investigated by X-ray diffraction, and several structural features are different from the previously described structure of the corresponding N adduct. The carbonyl group of the enaminone moiety of the C adduct is not coplanar with the enamine fragment. One bifurcated intramolecular NÐH O hydrogen bond [2.688 (2) and 2.668 (2) A Ê ] and two intermolecular CÐH O hydrogen bonds [3.339 (3) and 3.379 (3) A Ê ] are observed. The structure packs in a linear fashion along the [100] direction. |
