organic compounds
The title compound, C18H23NO2, is the final compound in the reaction between an ethynyl Fischer carbene and a 2-azadiene. The reaction proceeds to the stereoselective formation of a 2-azafluorenone. The structure determination reveals hydrogen bonding linking the carbonyl O atom and the H atom attached to the N atoms of symmetry-related molecules. As a result, the structure packing is composed of dimers connected by two hydrogen bonds. These hydrogen bonds show a similar geometry to those found between pairs of bases in DNA, and the structure itself resembles some synthetic inhibitors of DNA transcription.
