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 to afford the aldehyde, and then reacted with 4-methylbenzoyl hydrazine (1.0 mmol), and two drops of HOAc in EtOH (10 mL) at 80 °C. Suitable colorless block crystals of this compound were then obtained after recrystallization from methanol.

Experimental details

The structure was solved with the Olex2 program [2] as an interface together with the SHELXT and SHELXL programs [3], [4]. All non-hydrogen atoms were assigned anisotropic displacement parameters in the refinement. Hydrogen atoms were treated using a riding model.

Comment

Coumarins were natural products with diverse bioactivities such as anti-tumor [5], anti-inflammatory [6] and antimicrobial activity [7]. On the other hand, recent studies show that introduction of hydrazone fragments into natural products could displayed the remarkable biological activity [8], [9]. In order to discover more compounds with potential bioactivities we prepared a coumarin-based hydrazone derivative by introduction of hydrazone moiety into the coumarin.

The asymmetric unit of the title structure consists of two crystallographically independent molecules (cf. the figure). Geometric parameters of the title structure are in the usual ranges [10]. The compound contains one methoxy group, one lactone and two methyl-groups. The length of C—C double bond are, longer than the length of C—N double bond. Both of the configuration of the C—C double bond and the configuration C—N double bond are in type E, as well as the similar structure that reported [11].
