Source of materials
The title compound was available according to our earlier report [4]. An amount of 0.635 g (6 mmol) trimethoxymethane and 0.92 g (5 mmol) 1,5-dioxaspiro[5.5]undecane-2,4-dione were stirred in ethanol (15 mL) for 2.5 h at reflux temperature. Then 0.47 g (5 mmol) of benzenamine was added. The mixture was heated under reflux for another 5 h. The yellow precipitate was filtered off and dried. (M.p. 395.9–396.6 K). The crystals were collected by evaporation for ethanol after two days.
Experimental details
All H atoms were refined with riding coordinates. The H atoms of phenylamino ring were refined with the C—H distance restrained to 0.93 Å, N—H distance restrained to 0.86 Å, (AFIX 43 option of the SHELXL program [2, 3] ). However, the H atoms of CH2-groups in the cyclohexane ring were refined with the C—H distance restrained to 0.97 Å, (AFIX 23 option of the SHELXL program [2, 3] ). The Uiso(H) values of all hydrogen atoms were set to 1.2Ueq.
Discussion
Many spiro compounds possessing high biological activities have been synthesized over the past decades. Recently, spiro compounds containing oxygen are increasingly being studied due to their biological activities such as antitumor [5, 6] , antibiotic [7, 8] , insecticidal [9], anti-breast cancer activities [10], anisochronic properties etc.
Crystallographic studies show that the title compound belongs to triclinic crystal system, with space group P1̅. As can be seen from the crystal structure of the title compound (cf. the figure), the title molecule consists of a 1,5-dioxaspiro[5.5]undecane-2,4-dione group and phenylamino ring in the asymmetric unit, which are connected with the central C(7) atom. The C7—C9 bond length of 1.3833(15) Å has double-bond character. The N1—C7—C9 bond angle is 126.38(11)°, which resembles to an earlier reported structure [4]. The C1—N1—C7—C9 torsion angles of 179.44(11)° documents the planarity of this moiety. The 1,3-dioxane ring is in an envelope conformation. The cyclohexane ring adopts a chair conformation. The molecules are connected via one type of a N—H⋯O hydrogen bond. The N⋯O distance of 2.7581(14) Å indicates the hydrogen bond to be medium strong.
