Source of material

In a representative experiment 7-methoxy-8-(3-methylbut-2-en-1-yl)-2H-chromen-2-one (1.0 mmol) reacted with SeO2 (1.1 mmol) in dioxane (10 mL) at 80 °C, and then reacted with sodium borohydride at 0 °C to give the corresponding alcohol. Finally, a mixture of the aldehyde, 4-nitrobenzoic acid, N,N′-dicyclohexylcarbodiimide and 4-dimethylaminopyridine in dry dichloromethane was stirred at room temperature. Suitable colorless block crystals of this compound were obtained after recrystallization from methanol.

Experimental details

All non-hydrogen atoms were assigned anisotropic displacement parameters in the refinement. Hydrogen atoms were treated using a riding model.

Discussion

Coumarins are natural products with diverse bioactivities such as anti-inflammatory [5], anti-tumor [6], and antimicrobial activity [7]. Recently, we prepared a coumarin-based hydrazone derivative by introduction of hydrazone moiety into the coumarin [8]. Here we introduced the 4-nitrobenzoate moiety at the coumarin to find compounds with potential activity.

There is one cystallographically independent molecule in the asymmetric unit, and all bond lengths are in mormal ranges and they are similar with the known compound [9]. The compound contains one methoxy group, one lactone, one methyl-group and one C—C double bond. The length of C—C double bond (atoms C11—C12) was 1.423(3) Å. In addition, the configuration of the C—C double bond is in E configuration.
