The possibility of a single-stage solvent-free stereoselective synthesis of a spirocyclic compound from the natural bicyclic monoterpenoid (-)-fenchone and anthranilamide has been shown for the first time. The molecular and crystal structure of (1R,2S,4S)-1,3,3-trimethyl-10H-spiro[bicyclo[2.2.1]heptane-2,2'-quinazolin]-4'(3'H)-one, C17H22N2O, was established by X-ray diffraction though the chirality was assumed via the known reactant connectivity and H-1 and C-13 NMR spectroscopy. It has shown that in the molecule, for steric reasons, there is an elongation of the Me2C-C(N)N bond to 1.603 (5) A degrees. The formation of dimers via N-H center dot center dot center dot O C hydrogen bonds with an interaction energy of 93.30 kJ mol(-1) and through cavities (33.7% of the unit-cell volume) was established in the packing of the molecules. There are no pi-stacking interactions in the structure.
