An anhydrous Et2NH (10 mL) solution of dicyclohexylphosphinomethylpyridine-borane complex (280 mg, 0.923 mmol) was heated at 65C for 48 h under Ar. The solution was cooled to room temperature and Et2NH was removed in vacuo (ca. 10 mmHg, room temperature). To the residue was added sequentially dichlorotris(triphenylphosphino)ruthenium (II) (442.5 mg, 0.46 mmol) and an anhydrous toluene (10 mL). The resulting mixture was heated at 110C for 5 h under Ar, and was cooled to room temperature. Then to the mixture was added an anhydrous hexane (20 mL) to afford the yellow suspension. The mixture of the suspension was stirred at room temperature for 12 h and filtered through a filtration paper.

The crystals for the X-ray diffraction measurement were obtained by slow diffusion of Et2O in a saturated solution of CH2Cl2. The two derivatives exhibit a different geometry considering the 8-quinolinolate substituents. In derivative 3, the oxygen atoms of the two quinolinolates are orientated trans to each other, while in derivative 4 these trans positions are occupied by an oxygen and a nitrogen atom of the two different quinolinolates.

Example 13 Synthesis of (3S)-3-(1,3-benzodioxol-5-yl)-3-[({1-[2-oxo-3-(phenylmethyl)-1(2H)-pyridinyl]cyclohexyl}carbonyl)amino]propanoic Acid Step One: To a solution of 3-benzylpyridine (1.65 g, 9.77 mmol) in acetone (3.5 mL), 1-chloro-2,4-dinitrobenzene (2.00 g, 9.56 mmol) was added and the mixture was refluxed overnight. The mixture was cooled to room temperature, diluted with acetone and the solvent was decanted from the precipitate. The crude solid was washed with acetone (2 times) and diethyl ether (1 time), decanting each time to give 37(3.57 g, 100percent) as a gray solid. Step Two: To a solution of 1-amino-1-hydroxymethylcyclohexane (0.45 g, 3.5 mmol) in n-butanol (8.75 mL), solid N-(2,4-dintrophenyl)-3-benzylpyridinum chloride (37, 1.23 g, 3.3 mmol) was added. The resulting solution was heated to reflux for 2.5 days under a nitrogen atmosphere. The mixture was cooled, diluted with water and filtered. The filtrate was basified with concentrated NH4OH (2 mL) and extracted with ethyl acetate. The aqueous layer was concentrated to dryness to give 38(0.56 g) as a yellow oil which was used without further purification. Step Three: To a solution of crude 38(0.56 g, 3.5 mmol theoretical) in water (10 mL), a solution of potassium ferricyanide (3.3 g, 10 mmol) in water (15 mL) was added dropwise via an addition funnel over 30 minutes at 0¡ã C. A solution of KOH (0.76 g, 13.5 mmol) in water (5 mL) was then added over 30 minutes. Toluene (10 mL) was added and the solution was stirred for one hour at 0¡ã C. The layers were separated, and the aqueous layer was extracted again with toluene. The combined extracts were dried over Na2SO4 and filtered and the filtrate was concentrated under reduced pressure. The residue was chromatographed on silica gel, eluding with 7:13 hexanes:ethyl acetate to give 39(20 mg, 1.9percent, two steps.) Step Four: To a suspension of 39(20 mg, 0.068 mmol) in aqueous KOH (1M, 0.70 mL) potassium persulfate (0.073 g, 0.270 mmol) and ruthenium (III) chloride (1 mg, catalytic) and THF (0.25 mL) were added. The mixture was stirred for 1 hour and extracted with dichloromethane. The aqueous layer was acidified and extracted with ethyl acetate (3 times). The ethyl acetate extracts were combined, dried over MgSO4 and filtered. The filtrate was concentrated under reduced pressure to give 40(0.0148 g, 70percent) as a tan solid. (3S)-3-(1,3-Benzodioxol-5-yl)-3-[({1-[2-oxo-3-(phenylmethyl)-1(2H)-pyridinyl]cyclohexyl}carbonyl)amino]propanoic acid was prepared from 40according to the procedures described in Example 1. 1H NMR (400 MHz, CD3SO2CD3): delta 1.40 (m, 4H), 1.68 (m, 2H), 2.04 (m, 2H), 2.60 (d, J=7.0 Hz, 2H), 3.67 (d, J=15.2 Hz, 1H), 3.72 (d, J=15.2 Hz, 1H), 5.12 (m, 1H), 5.95 (m, 2H), 6.19 (t, J=7.0 Hz, 1H), 6.74 (dd, J=7.8, 1.4 Hz, 1H), 6.76 (d, J=7.8 Hz, 1H), 6.90 (d, J=1.4 Hz, 1H), 7.10 (d, J=5.8 Hz, 1H), 7.20 (m, 5H), 7.57 (d, J=8.4Hz, 1H), 7.66 (dd, J=7.7, 1.8 Hz, 1H).
