| In ethanol; for 1.0h;Reflux; | General procedure: An equimolar mixture of 4-substituted aniline (1) (10.0 g, 0.078 mol), 4-fluorobenzaldehyde (2) (9.72 g, 0.078 mol) in ethanol (100 mL) were refluxed for 1 h, pyruvic acid (10.30 g, 0.117 mol) and trifluoroacetic acid (1 mL) were then added to the reaction mass and further refluxed for 12 h. After completion of the reaction, the reaction mixture was poured into ice-cold water. The solid product obtained was filtered, washed with water and recrystallized using ethanol. | |
| In chlorobenzene; for 1.0h;Reflux; | General procedure: In a 25 mL round-bottom flask, amine (0.8 mmol, 1.0 equiv.) and aldehyde (0.9 mmol, 1.1equiv.) were dissolved in 10 mL of chlorobenzene and refluxed with azeotropic removal of water. After 1 h, half of the solvent was distilled off and 2-diazomalonate (4a-e), 1.6 mmol,2.0 equiv.) was added. The mixture was then refluxed overnight, and the reaction progress was followed via TLC. When no more diazo compound was detectable (20-24 h), the solvent was evaporated in vacuo and the resulting mixture was purified by column chromatography on silica gel with a linear gradient (0-20%) of acetone in n-hexane (total volume of eluent,450 mL) to provide pure compounds 6a-p. In case of volatile aldehyde or amine, they were reacted in chlorobenzene at room temperature overnight in the presence of 4 Å molecular sieves. The latter was filtered off before proceeding with the addition of 4 and heating. Compounds 6a, 6d, 6g, 6l, 6n, 6p were prepared with the use of presynthesized imines. |

| In water; | General procedure: General procedures for the syntheses of the iminesMethod A: To a solution of the aniline derivative (1 eq) in abs. ethanol the corresponding aldehyde (1 eq) was added and stirred for 3 h at room temperature. The solvent was evaporated and the crude product was purified by crystallization (3a-c). Method B: The aniline derivative (1 eq) was dissolved in a mixture of ethyl L-lactate and water, and the corresponding aldehyde (1 eq) was added. The solution was stirred till all compounds were dissolved. The immediately formed crystals were filtered, washed with cold water and dried in vacuo to give the product. (3d-h) |

| With acetic anhydride; chlorobenzene; at 110℃; for 16.0h;Sealed tube; | General procedure: Corresponding diacid 3b-e (1 mmol) was placed in a screw-cap vial, followed by addition of PhCl (2 mL), imine (1.1 mmol, 1.1 equiv.) and acetic anhydride (120 mg, 1.2 mmol, 1.2 equiv.). The resulting suspension was placed in a pre-heated oil bath (130 C) and stirred for 16 h. After cooling to room temperature, the reaction mixture was transferred to a round-bottom flask and concentrated in vacuo. The residue was dissolved in DCM (20 mL) and extracted with aq. NaHCO3 sat. twice (10 + 5 mL). Combined aqueous layer was cooled to 0 C followed by careful addition of HClconc to adjust pH to 1. The precipitate formed was filtered, washed with water (10×3 mL) and dried under air to obtain pure products 5-20. |
