76% With sodium hydride; In tetrahydrofuran; at 60.0℃; for 16.0h;Inert atmosphere; Under argon, to a suspension of sodium hydride (60% dispersion in mineral oil, 2.0 g,50 mmol) in dry THF (200 ml) 2-acetylpyridine (5.0 g, 41.3 mmol) and ethyl 2-pyridinecarboxylate (6.24 g, 41.3 mmol) were added. The reaction mixture was slowly heated to60 C in the course of 1 h and then kept at this temperature for 15 h. During this time, a fineyellow suspension was formed. The mixture was cooled to 0-5 C, filtered off, washed withTHF (50 ml) and dried to afford the sodium salt of 1a as a beige powder. Then this materialwas suspended in water (300 ml) and acetic acid (3.2 ml, 55.9 mmol) was slowly added withstirring. The thick suspension formed was filtered off, the remaining product was washedwith water (150 ml), and dried to afford 7.10 g (76%) of an off-white solid: mp 100 C (lit.1 mp 100-101 C).
With sodium hydride; In tetrahydrofuran; for 12.0h;Reflux; Inert atmosphere; 1-(Pyridin-2-yl)ethanone (1.26 g, 10.4 mmol) and esters(20.8 mmol, 2.0 equiv) were slowly added to a stirred suspension ofsodium hydride (0.50 g, 20.8 mmol) in dry tetrahydrofuran (THF)(50 mL) at 0 C. After the mixture was refluxed for 12 h, it was quenchedwith 2 N HCl until pH value to 5-6 and extracted three times withethyl acetate (EtOAc). The organic phase was washed with brine, driedover Na2SO4, and concentrated under vacuum to yield the crude 1, 3-dione.

The solution is subsequently evaporated to dryness in a rotary evaporator. The residue is dissolved in THF and filtered through a short silica-gel bed. The solvent is then removed by means of vacuum. The solid is subsequently recrystallised from heptane/THF and subsequently extracted with hot heptane/toluene over aluminium oxide. The solid which precipitates out on cooling is filtered and dried.

YieldReaction ConditionsOperation in experiment
In ethanol; Ligand L (0.25 g, 1.17 mmol) and CdI2 (0.43 g, 1.17 mmol) were dissolved separately in acetonitrile (5 mL). The solutions were mixed, ethanol(10 mL) was added, and the solutions were kept for several hours at room temperature. As the solvents evaporated, the solution turned dark brown and a solid phase was isolated as fine needle-like crystals with inclusions of elemental iodine. The solid phase was filteredoff, repeatedly dissolved in an acetonitrile-ethanol(1 : 1) mixture, filtered to separate iodine impurities, and kept in air at room temperature until the most part of solvents was removed. The formed crystals were filtered off, washed with a minor amount of acetonitrile, and dried in air. The crystals were not suitable for X-ray diffraction analysis.

With toluene-4-sulfonic acid In toluene at 100℃; Dean-Stark; 157; 160-168 The specific preparation process is: General procedure: 0.5g (1.71mmol) octahydrobinaphthalene diamine (H8-BINAM) and 0.43g (4.28mmol) acetylacetone (3g: R1, R3=CH3) were placed in a 50ml single-necked bottle,Add 25ml of toluene and a catalytic amount (0.025g) of p-toluenesulfonic acid (TsOH),Then install the water separator (which is filled with solvent), and magnetically stir to raise the temperature to about 100°C, so that it can fully reflux. After 10 hours, TLC was used to detect the complete reaction of the raw material octahydrobinaphthyldiamine, the reaction was terminated, and the solvent was removed by rotary evaporation to obtain an intermediate (5 g). Add 15 g of polyphosphoric acid (PPA) and mechanically stir at 145° C. for 6 h. Add ice water to quench the reaction, and then add sodium hydroxide solution to make it alkaline (pH=~10). Suction filtration, the filter cake is recrystallized with n-hexane to obtain the target product (C-II-a).
