After additional stirring for 30 min, a solution of cinnamaldehydes (2 mmol) in ether (5 ml) was added dropwise over 15 min and stirred at 0°C. The reaction progress was monitored by thin layer chromatography. After completion of the reaction dilute HCl was added to the reaction mixture. The organic phase was extracted with ether (2×30 ml), then washed with water (2×20 ml) and dried (Na2SO4). Then the solvent was removed and the product was purified by flash column using petroleum ether-ethyl acetate mixture as eluent to afford corresponded products.

Stage #1: diethyl p-nitrobenzylphosphonate With sodium hydride In tetrahydrofuran at 0℃; for 0.0833333h; Stage #2: 4-methyl-cinnamaldehyde In tetrahydrofuran at 0℃; for 0.5h; 2.1 Synthesis General procedure: Diphenylbutadiene derivatives utilized in this investigation were prepared by using Horner-Wadsworth-Emmons reaction [23] (Scheme 1a) in about 35-60% yields. In a typical procedure, triethyl phosphite (5.74 mmol) was added to the THF solution of benzyl bromide (2.3 mmol) and refluxed for 24 h under a N2 atmosphere. The reaction mixture was cooled to room temperature and further cooled to 0 °C using an ice bath. Sodium hydride (11.5mmol) was added to this mixture and stirred for 5 min. Aldehyde (2.3 mmol) was subsequently added drop wise to the pale/dark pink colored solution and stirring was continued for additional 30 min. In the case of methyl substituted aldehydes, corresponding (E) geometric isomer of α-methyl cinnamaldehyde (Aldrich) was used. Thin Layer Chromatography (TLC) was utilized to monitor the progress of the reaction and the reaction was quenched by adding water. The organic layer was extracted using dichloromethane and concentrated under reduced pressure. The crude reaction mixture so obtained was purified by column chromatography using silica gel, 5% ethyl acetate in petroleum ether. Starting materials, 4-methylcinnamaldehyde required for the synthesis of ( 2) and nitro cinnamaldehyde required for synthesis of (3) and (5), were obtained by DDQ oxidation of 4-allyl toluene [40] (Scheme 1b) and by simple nitration using a nitrating mixture generated by mixing KNO3 with H2SO4 of α-methyl-cinnamaldehyde (scheme 1c), respectively. Characterization data for all the synthesized dienes were given in the Supplementary information.

The reaction mixture was stirred vigurously for 24 hours at 0 oC, then α,β-unsaturated aldehyde (3, 0.6 mmol) and morpholine (cat. 7e, 50 mol %) were added successfully. After 24 hours, the reaction mixture was purified on silica gel to afford the desired product directly. The racemic samples were prepared by using the mixture of quinine and quinidine (1:1, 20 mol %), morpholine (50 mol %) as the catalyst combination.
