1 Source of material

We selected the hydroxyl aromatic ketonether derivate present in A. crenata Sim as the raw material to synthesize the title compound. 1-(2-hydroxy-4,6-dimethoxyphenyl)ethan-1-one (1.96 g, 10 mmol) and dimethylformamide dimethylacetal (6.0 mL) were combined. The dark red solution was heated to 383 K. Thin layer chromatography tracked the reaction. The dark red solution precipitated red solid when cooled to room temperature. The mixture was filtered and concentrated in vacuo to afford a red solid. The red solid was recrystallized with ethanol.

2 Experimental details

The carbon-bound hydrogen atoms were placed in their geometrically idealized positions and constrained to ride on their parent atoms.

3 Comment

Enaminones and its derivatives are widely used in the field of organic and pharmaceutical chemistry [4]. In the past decade, enaminone compounds have been well documented as potential anticonvulsants and potential multidrug resistance regulators [5], [6], [7]. Enaminone compounds also can be used as potent allosteric modulators of γ-aminobutyric acidA (GABAA) receptors [8]. Cyclic, six-membered enaminones represent a class of molecules that demonstrate unique chemical and biological properties [9]. In addition, in our research of the identification of key genes involved in the biosynthesis of secondary metabolites in A. crenata Sim based on high-throughput sequencing technology and identification of antiseptic genes of pinellia, two important national Chinese medicinal materials, analyzing the differential genes and proteins involved in the biosynthesis of secondary metabolites of A. crenata Sim through high-throughput sequencing technology, cloning the related genes of anti-rot and correlation analysis between yield, quality of pinellia ternata. We found that enaminone compounds are also present in Guizhou’s A. crenata Sim and pinellia ternata. Enaminone compounds are also used raw material to synthesize flavonoids in A. crenata Sim and pinellia ternata. Therefore, the synthesis and modification of enaminone compounds has been a hot topic. The structure of the title compound is a kind of enaminone, containing a benzene ring, a hydroxyl group, two methoxys, a ketone and an enamine. The bond lengths and angles derived from the title structure are within normal ranges and consistent with those reported previously in similar structures [1013]. The keto group was confirmed by the distance of 1.269(3) Å (C7–O3), the phenolic hydroxyl was confirmed by the distance of 1.336(3) Å (C2–O2), the C8=C9 double bond adopts a E-configuration and the bond distance is 1.369(3) Å, the bond distance of the N1–C9 is 1.327(3) Å. The torsion angle of O1–C4–C5–C6 and C2–C1–C6–O4 are −179.5(2)° and −179.74(18)°, respectively.
