Source of material

A mixture of acetone (1.00 g, 17.2 mmol), 4-chlorobenzaldehyde (4.80 g, 34.5 mmol) and KOH (50%) in methanol 50 (mL) was stirred at room temperature for 2 h and then quenched with ice-cold water. The resultant precipitate was filtered on a sintered funnel and then recrystallized from ethanol to afford the title compound as an orange solid (4.31 g, 83%), m.p. 263 K (EtOH); IR νmax (ATR) 601, 708, 823, 979, 1012, 1217, 1365, 1407, 1490, 1585, 1648 cm−1; 1H-NMR: δH (500 MHz, CDCl3) 7.03 (2H, d, J = 16.0 Hz, α-H), 7.39 (4H, d, J = 8.0 Hz, Ar), 7.53 (4H, d, J = 7.5 Hz, Ar), 7.67 (2H, d, J = 16.0 Hz, β-H); 13C-NMR: δC (125 MHz, CDCl3) 125.7 (2xC), 129.3 (2xC), 129.5 (2xC), 133.1, 133.2, 136.5, 142.0 (2xC), 147.4, 188.3; HRMS (ES): MH+, found. 306.0236 C17H13Cl2O+ requires: 302.0265.

Experimental details

Hydrogen atoms were positioned geometrically and allowed to ride on their respective parent atoms with d(C–H) = 0.95 Å and Uiso(H) = 1.2Ueq(C).

Discussion

Curcumin (1,7-bis(4-hydroxy-3-methoxyphenyl)-1,6-heptadiene-3,5-dione) was first isolated from the plant Curcuma longa two centuries ago and has the potential to treat a wide variety of inflammatory diseases including diabetes, cardiovascular diseases, arthritis and Alzheimer’s disease [4, 5] . Its antioxidant properties and its ability to inhibit the nuclear factor-kappaB (NFkB), which modulates several pro-inflammatory and profibrotic cytokines provide a rational molecular basis to use it in hepatic disorders [4]. The enone analogues with the 5-carbon spacer (1,1′-distyryl ketones) were found to significantly inhibit the TNFα-induced activation of the transcription factor NFkB more so than curcumin [6]. Analogues of 1,1′-distyryl ketones devoid of phenolic groups have also been found to exhibit significant anti-oxidant properties [7]. The analogous (1E,4E)-1,5-bis(4-hydroxyphenyl)penta-1,4-dien-3-one and (1E,4E)-1-(2-hydroxyphenyl)-5-phenylpenta-1,4-dien-3-one, on the other hand, have been found to exhibit significant larvicidal activity against mosquito Aedes aegypti (L), [8] a known vector in the transmission of yellow fever, dengue haemorrhagic fever, and the re-emerging disease chikungunya. These compounds have also been found to inhibit binding of cholesterol to Aedes aegypti SCP-2 (AeSCP-2) in vitro [9]. To-date, the structures of the 1,1′-distyryl ketones have only been fully characterised using 1H-NMR, 13C-NMR, IR and UV spectrometric techniques and their trans stereochemistry was assigned based on the coupling constant values, Jtrans = 15.0–16.5 Hz [10]. We have been able to prepare (1E,4E)-1,5-bis(4-chlorophenyl)penta-1,4-dien-3-one via a base catalysed Claisen-Shmidt condensation of acetone (1 equivalent) with 4-chlorobenzaldehyde (2 equivalents) and obtained crystals of this compound.

The two aryl rings in the title structure (cf. the figure) are planar with the torsion angle about the C(1)—C(7)—C(8)—C(9) backbone (174.7°) nearly equal to but opposite in sense to that about the C(9)—C(10)—C(11)—C(12) backbone (−173.1°). The C=O bond length (1.220(3) Å) is in the typical range for chalcones [11].
