Source of material

The synthetic process are as follows: firstly, paeonol (0.5 g; 3.01 mmol) and anhydrous pyridine (0.50 g; 6 mmol) were dissolved in 10 ml methylene chloride at −10 °C under nitrogen protection. Secondly, triphosgene (0.9 g; 3.1 mmol) was dissolved in 5 mL dichloromethane, then added dropwise at room temperature. The reaction proceeded for 3–4 h, monitored by Thin-Layer Chromatography (TLC). Furthermore, the pyridine salt was filtered off and 50 mL ethyl acetate was added to extract, and the extracted organic phase was treated by distilled water washing, anhydrous sodium sulfate drying and vacuum distillation. Finally, column chromatography with petroleum ether and ethyl acetate in a molar ratio of 6:1 was adopted to obtain the white final compound, which crystallized for several days at room temperature, giving colorless block crystals.

Experimental details

The structure was treated with the olex2 crystallographic software package, solved with the ShelXT [5] structure solution program using Intrinsic Phasing and refined with the SHELXL [5] refinement package. Carbon-bound hydrogen atoms were placed in calculated positions and refined with riding coordinates, with Uiso(H) fixed at 1.2 times of Ueq(C).

Comment

2-Hydroxy-4-methoxyacetophenone also known as paeonol or peonol, is obtained from the dried root bark of Xu Changqing or peony. Additionally, it has various bioactivities, such as antineoplastic, whitening, antiallergic, anti-inflammatory, analgesic and anti-virus effect [6]. At the same time, the presence of phenolic hydroxyl groups causes paeonol to be irritating, and thus limiting its further development for clinical applications. Consequently, bis(2-acetyl-5-methoxyphenyl) carbonate was synthesized by coupling the formyl group as well as phenolic hydroxyl of paeonol, which can improve the lipid solubility and bioavailability [7], [8], [9].

The structure of diphenylcarbonate have been reported, in which a diphenylcarbonate structure, a 2-nitrophenyl phenoxyformate structure, a bis(o-nitrophenyl) carbonate structure and a bis(2-methoxyphenyl) carbonate structure were described [10], [11], [12], [13].

The asymmetric unit contains one complete organic molecule, two halfs of that molecule, located on twofold axis and three water molecules. The title compound bis(2-acetyl-5-methoxyphenyl) carbonate is shown in the figure, with two paeonol fragments connected by carbonyl groups. Based on the diphenylcarbonate structure [10], there is an acetyl and a methoxy at each phenyl group. The phenyl rings are bent towards the double bonded oxygen atom on the central carbon atom. Moreover, the mean bond angles for O=C–O, O–C–O, C–C=O and C–O–C are 127.15°, 105.66°, 120.78° and 117.94° respectively, closely resembling to the reported ones [12]. The ester bond lengths of C8–O2, C17–O6 and C10–O4 are 1.220, 1.223 and 1.182 Å (consistent with [11]). The average ether bond length is 1.381 Å, moreover, the C–O ether bond lengths are similar to the reported ones in [11, 13].
