An amount of 1.6 mmol of 5α-pregnane-3,20-dione was weighed and placed in a 25 ml round-bottom flask. 1.3 mmol of 2-methoxyaniline, a drop of acetic acid, and 10 ml of methanol were added. The mixture was stirred for 24 h at room temperature, then 3.9 mmol of NaBH4 was slowly added, which was further allowed to stir for 3 h. At the end of the reaction, the reaction mixture was extracted by ethyl acetate and washed with brine. In addition, the combined organic layers were dried with anhydrous magnesium sulfate. After filtration, the colorless bulk crystal of the title compound was obtained by crystallization of the crude product in methanol with a yield of 56 %. Elemental analysis calcd.

2 Comment

Plants of the species Sarcococca ruscifolia of Buxaceae are widely used as ethno medicine in many parts of China. With the effect of cooling blood and removing stasis, detoxifying sores, and so on, it is mainly used to treat common ailments such as stomach pain, bruises, rheumatic pain, sore throat, etc. [5]. For example, in the Miao region of Guizhou, the unilateral prescription of this species is often used to treat Alzheimer’s disease [6]. Modern studies have revealed that S.  ruscifolia plants are rich in pregnane-type alkaloids, which have a variety of pharmacological activities [7], [8], [9], [10], [11]. In order to find high-efficiency, low-toxicity, and safe alkaloid derivatives, we used 5α-pregnane-3,20-dione as the substrate for derivatization. As a result, we introduced o-methylaniline at the C-3 position to obtain the title compound. This study has explored new ideas for the subsequent research of this type of alkaloid.

The compound consists of one keto, two methyls, one o-methoxyaniline, and four rings of A, B, C, and D of the steroid parent nucleus. The A/B and C/D rings in the mother nucleus are all cis-fused. The B/C rings are trans-fused, and the substituents on positions C-10, C-13, and C-17 are all in β configurations. The o-methoxyaniline system at position C-3 is in a α configuration. The bond length and bond angle of the compound are within the normal range [11]. The o-methoxyaniline system is planar, and the carbonyl is confirmed by the distance d (C20–O1) = 1.204(4) Å. The five membered ring and three six membered rings show intermolecular interactions by van der Waals forces only.
