Source of materials

A mixture of 4-hydroxycoumarin (10 mmol), 3-bromobenzaldehyde (10 mmol), ethyl cyanoacetate (10 mmol) and 4-(dimethylamino)pyridine (DMAP) (1 mmol) in ethanol (100 mL) was refluxed for 2–3 h and then cooled to room temperature. After filtering the precipitates, they were sequentially washed with ice-cooled water and ethanol and then dried under a vacuum.

Experimental details

H atoms bonded to C and N atoms were positioned geometrically and refined using a riding model, with C—H = 0.93/0.96/0.97 Å and N—H = 0.86 Å with Uiso(H) = 1.2 × Ueq(C) and 1.2 × Ueq(N).

Comment

Coumarin derivatives possess several types of pharmacological properties such as anticancer, anti-HIV, anticoagulant, spasmolytic, and antibacterial activity [4]. Pneumonia is an inflammatory condition of the lung affecting primarily the small air sacs known as alveoli. Recent research has indicated that quinoline derivatives and related classes of compounds like the title molecule are potentially effective in treatment to shrink pneumonia and control symptoms [5].

The molecular structure of the title compound is shown in the Figure. In its structure, the angle of six-membered ring constructed by C16-21 atoms and the six-membered ring constructed by C4—C8 and O3 atoms is 88.5°. The bond distances and angles presented in the title compound are all in their normal scopes. The features of the title compound are comparable with those of the compound ethyl 2-amino-4-(2-methoxyphenyl)-5-oxo-4H,5H-pyrano[3,2-c] chromene-3-carboxylate [6]. The main differences results from the exchange of one functional group: there is -OCH3 in ethyl 2-amino-4-(2-methoxyphenyl)-5-oxo-4H,5H-pyrano[3,2-c] chromene-3-carboxylate, while in the title compound, one Br atom could be found. The structural parameters of the title compound are also in excellent accord with compounds that lacks the benzo moiety [7].
