Short Note ( E ) - 3 - Methyl - 6 - ( 3 - oxo - 3 - ( thiophen - 2 - yl ) - 1 - propenyl ) - 2 ( 3 H ) - benzothiazolone
The title compound, (E)-3-methyl-6-(3-oxo-3-(thiophen-2-yl)-1-propenyl)-2(3H)-benzothiazolone, was synthesized by Claisen-Schmidt condensation of 3-methyl-2(3H)-benzothiazolone-6-carbaldehyde with 2-acetylthiophene in 94% yield. The structure of the target compound was confirmed using 1H-NMR, 13C-NMR, IR, MS, and elemental analysis.

In the title compound, C(15)H(14)O(4), the chromone ring system is close to being planar [maximum deviation = 0.015 (2) Å]. The double bond of the ethyl prop-2-enoate chain adopts an E conformation and an intra-molecular C-H⋯O hydrogen bond generates an S6 ring. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R(2) (2)(14) loops. Weak π-π inter-actions [centroid...
