1 Source of material
The title compound was prepared from the reaction of 8-(hexyloxy)-3,6-dimethyl-1-(piperidin-1-yl)isoquinoline-7-carbonitrile, which was obtained according to the published method [5], and selenium dioxide. The mixture of the aforementioned carbonitrile (1.0 mmol), selenium dioxide (3.0 mmol), and xylene (15.0 mL) was stirred for 12 h at 100 °C. After the reaction solution was cooled to room temperature, it was extracted with dichloromethane. After removing the solvent under reduced pressure, the crude product was purified by column chromatography using petroleum ether and ethyl acetate to obtain the target product in 62 % yield as light yellow solid. Crystals were obtained by a slow evaporation from a mixture of ethyl acetate and petroleum ether.
2 Experimental details
H atoms bonded to C were positioned geometrically and refined using a riding model, with Uiso(H) = 1.5 Ueq(C) for methyl H atoms and 1.2 Ueq(C) for all other H atoms.
3 Comment
In recent years, the design and synthesis of 4H-pyran derivatives substituted with multiple aromatic rings have received widespread attention because some of these compounds exhibited interesting solid-state photochromic property [6], mechanofluorochromic property [7, 8], and room – temperature phosphorescence activity [9]. The compounds usually have twisted molecular conformations and loose stacking arrangements in crystalline state, capable of emitting solid-state fluorescence. More importantly, their morphology is easily affected by external stimuli, exhibiting solid-state fluorescence response properties. Obviously, the crystalline structural characteristics of these compounds warrant further research to obtain more diverse 4H-pyran-based organic materials. In the title compound, the 4-position benzene ring is perpendicular to the 5-position benzene ring, and the dihedral angle between the 5-position benzene ring and the 6-position benzofuran unit is 66°. Due to incomplete conjugation, the atoms of the central 3,4-dihydro-2H-pyran-2-one ring are not in the same plane. The results indicate that the molecule has a twisted molecular conformation, which is similar to previous reports in the literature [6], [7], [8], [9]. As a result, no obvious π–π stacking is observed even though in the presence of multiple aromatic rings. In the same column, the molecules in the upper and lower layers are connected to each other through C12–H12⃛O2 (2.384 Å), C7–H7⃛O1 (2.613 Å), and C22–H22⃛O2 (2.710 Å) hydrogen bonds. The molecules in different columns are linked by C2–H2⃛N1 (2.688 Å) hydrogen bond.
