Source of material

Benzyl bromide (342 mg, 2.0 mmol) and anhydrous potassium carbonate (277 mg, 2.0 mmol) were added to a solution 1-(adamantan-1-yl)-3-(3-chlorophenyl)thiourea (642 mg, 2.0 mmol), in acetone (10 mL), and the mixture was heated under reflux for 3 h. The solvent was distilled off in vacuo, and the residue was washed with water, dried and recrystallized from ethanol to yield 625 mg (76%) of the title compound as transparent block crystals. M.P.: 367–369 K. Single crystals were obtained by slow evaporation of a EtOH/CHCl3 (1:1) solution at room temperature. 1H-NMR (DMSO-d6, 700.17 MHz): δ 1.58–1.60 (m, 6H, adamantane-H), 1.98–2.0 (s, 9H, adamantane-H), 6.17 (s, 1H, NH), 6.50–6.54 (m, 2H, Ar—H, 6.92–6.93 (m, 1H, Ar—H), 7.16–7.18 (m, 1H, Ar—H), 7.27–7.30 (m, 5H, Ar—H). 13C-NMR (DMSO-d6, 176.08 MHz): δ 29.38, 36.09, 36.57, 41.10 (adamantane-C), 53.76 (benzylic CH2), 121.27, 121.51, 122.01, 127.26, 128.83, 129.27, 130.36, 133.10, 138.05, 148.38 (Ar—C), 152.16 (C = N). ESI-MS, m/z: 410.4 (M + H, 100%)+, 411.4 (M + 2 + H, 35%)+.

Experimental details

Carbon-bound hydrogen atoms were placed in calculated positions and were included in the refinement in the riding model approximation, with Uiso(H) set to 1.2Ueq(C).

The coordinates and the Uiso parameter of the hydrogen atom at the NH group were refined freely.

Discussion

Isothiourea derivatives were early recognized as compounds of particular value in medicinal chemistry. Several substituted isothiourea derivatives were reported to possess significant cardiovascular properties as nitric oxide synthase inhibitors [1], [2], [3], [4], [5], and calcium channel blockers [6]. Isothiourea derivatives were also reported to display potent antimicrobial [7, 8] , anticancer [9, 10] , and anti-anthelmintic [11] activities. The incorporation of the highly lipophilic adamantyl group positively modulates the therapeutic index of several compounds through various mechanisms [12, 13] . Various adamantane derivatives are known for their antiviral activity against the influenza A [14], [15], [16], human immunodeficiency (HIV) [17], [18], [19] and herpes simplex [20] viruses. Moreover, several adamantane-based drugs are currently used as useful therapies for the control central nervous disorders [21, 22] . In addition, potent antimicrobial [23], [24], [25], anticancer [26, 27] , anti-inflammatory [28, 29] and hypoglycemic [30] activities were reported for numerous adamantane-based derivatives. The present investigation describes the synthesis and the single crystal X-ray structural characteristics of the title adamantane-isothiourea hybrid molecule as potential chemotherapeutic agent.

The asymmetric unit of the title structure contains one independent molecule. The N2—C11 bond length is 1.272(3) Å which is typical carbon-nitrogen double bond, The molecule has a Z-configuration around this double bond (cf. the figure). All geometric parameters are in the expected ranges. The molecules are packed in the crystal structure without any intermolecular hydrogen bonds.
