摘要
A new spiro[indoline naphthaline]oxazine derivative, 12-methoxy-14,14-dimethyl-17-(piperidin-1-yl)-7,8,14,15a-tetrahydro-4bH-naphtho[1 '',2 '':5',6'][1,4]oxazino[3',2':2,3][1,4]oxazino[4,3-a]indole (1), was successfully synthesized, and its structure was characterized by H-1 NMR, C-13 NMR, IR, HRMS and single-crystal X-ray diffraction method. X-ray diffraction indicates that benzene and naphthalene rings of compound 1 are almost perpendicular, and the piperidine ring at the 6'-C site is in a chair conformation. In the packing diagram, a couple of short intermolecular distances such as the intermolecular short contact are observed. The photochromic properties of compound 1 have been fully investigated in different solvents, it was found that it exhibited excellent photochromism properties in solvents. (C) 2015 Elsevier B.V.
