Source of material
To a stirred solution of 6-methyl-2-oxo-2H-chromene-3-carboxylic acid (0.612 g, 3 mmol), N,N-Dimethylformamide (DMF) (0.007 g, 0.1 mmol) was added dropwise SOCl2 (2.975 g, 25 mmol) at 0 ∘C for 30 min, then enhanced to 95 ∘C for 4 h. The reaction was monitored by thin-layer chromatography (TLC). Next, unreacted SOCl2 was removed. Then 15 mL of anhydrous CH2Cl2 was added. Pyrrolidine (0.22 g, 3.1 mmol) and TEA (0.607 g, 6 mmol) were dissolved in 10 mL of anhydrous CH2Cl2. This solution was added dropwise to the reaction mixture at room temperature. The reaction was monitored by TLC. After, CH2Cl2 was removed. At last, the reaction mixture was allowed to recrystallize from methanol to obtain 6-methyl-3-(pyrrolidine-1-carbonyl)-2H-chromen-2-one.
Experimental details
All H atoms were included in calculated positions and refined as riding atoms, with C–H = 0.90–0.97 Å with U iso(H) = 1.5 U eq(C) for methyl H atoms and 1.2 U eq(C) for all other H atoms.
Comment
Coumarin and its derivatives are heterocyclic compounds with a benzopyrone structure [5, 6], which may have excellent antiviral [7], antioxidation [8] antibacterial [9, 10], anticancer [11] and many other physiological, pharmacological activities and optical properties [12]. Among them, coumarin-3-carboxylic acids are vital precursors for the synthesis of active compounds such as dicoumarol, fluorocoumarin carboxylate and coumarin amide [13, 14]. Therefore, it is a research hotspot to explore the efficient synthesis of coumarin-3-carboxylic acids [15], [16], [17].
In the molecule of the title compound (fig.), bond lengths and angles are very similar to those given in the literature for coumarin derivatives [15–18]. In the molecules of the title structure, the coumarin moiety is approximately planar. The dihedral angle between the coumarin moiety and the plane of amides part (C10–N1–O3) is 62.8°. The pyrrolidine part adopts an envelope conformation. The torsion angles of C8–C10–N1–C11, C10–N1–C11–C12, N1–C11–C12–C13, C11–C12–C13–C14 and C12–C13–C14–N1 are −7.0(2)°, −158.5(1)°, −33.7(2)°, 38.6(2)° and −27.7(2)°, respectively.
