Source of material

Benzyl 3β-acetylglycyrrhetate (systematic name: benzyl (2S,4aS,6aS,6bR,10S,12aS,12bR,14bS)-10-acetyl-10-hydroxy-2,4a,6a,6b,9,9,12a-heptamethyl-13-oxo-1,2,3,4,4a,5,6,6a,6b,7,8,8a,9,10,11,12,12a,12b,13,14b-icosahydropicene-2-carboxylate) is synthesized by two-step reaction in turn. Glycyrrhetinic acid was reacted with benzyl bromide and K2CO3 in DMF at room temperature for 1 h. The solution was dissolved in ice water and extracted with ethyl acetate. The organic phase was washed with brine, dried over Na2SO4. After filtration, the ethyl acetate was evaporated in vacuo to yield a transparent oil. Then the acetic anhydride and 4-dimethylaminopyridine was added to a stirred solution of the products in pyridine at room temperature. The resulting solution was stirred at r.t. for 2 h and then poured into ice water, resulting in the title compound as the white powder. Suitable crystals of the title compound were obtained by recrystallization in dichloromethane and methanol.

Experimental details

Hydrogen atoms were situated in idealized positions with the carrier atom-H distances = 0.93 Å for alkene and aryl, 0.96 Å for methyl, 0.97 Å for methylene and 0.98 Å for methine.

The U values of the hydrogen atoms of methyl groups were set to 1.5Ueq and the U values of all other hydrogen atoms were set to 1.2Ueq (C). The absolute configuration was derived from the synthesis.

Comment

18β-Glycyrrhetinic acid (GA) is the main metabolite of glycyrrhizin. The pentacyclic system of GA is composed of condensed six-membered rings and a five-membered ring. At present, the structural modification of this compound mainly focuses on the hydroxyl group at C-3, the carboxyl group at C-20, and the ketone functional group at C-11 [4]. It has been shown to have numerous pharmacological effects, such as anti-inflammatory [5], [6], anticancer [7], [8], antibacterial [9], antiviral [10]. The structural modification of glycyrrhetinic acid may be valuable in obtaining new chemical derivatives for pharmacological screening and structure-activity relationship studies.

The single-crystal which was measured is obtained by crystallization in dichloromethane and methanol solution. As shown in figure, for the title compound, all the rings adopt chair conformations, except the enone ring, which is flattened to a half-chair. The sole cis ring juncture, between the benzyl ester-bearing ring and its neighbor, confers little skeletal flexibility because two of the remaining ring junctures are trans and the third involves an alkene. Three carbon-oxygen double bond exist in the compound, the C—O bond distance (C3—O1) is 1.463(3) Å, the C—O bond distance (C38—O1) is 1.330(3) Å; the C—O double bond distance (C11—O2) is 1.216(3) Å; the C—O double bond distance (C29—O3) is 1.202(3) Å; the C—O bond distance (C29—O4) is 1.336(3) Å, the C—O bond distance (C31—O4) is 1.463(3) Å; the C—O double bond distance (C38—O5) is 1.194(4) Å. The O3—C29—O4, O5—C38—O1 angles are 123.0(2)°, 123.8(3)°, respectively. The bond lengths and angles are all in the expected ranges.
