The solution is heated to 50°C for 15 minutes before removing the solvent in vacuo to give a yellow crystalline solid. 18.65mg of (i?,i?)-DACH (0.1633 mmol) are added with 5ml of dry degassed tetrahydrofuran and heated at 60°C for 4 hours. The reaction is cooled to room temperature. 31P NMR reveals essentially a single species and no starting materials. 31P NMR reveals >96% product and conversion. The solvent is removed in vacuo to give a pale yellow amorphous solid.31P NMR (162 MHz, CDCl3) δ44.79 ppm, singlet. |

Stage #1: bis(1,5-cyclooctadiene)rhodium(I) tetrafluoroborate; 1,1′-binaphthalene-2,2′-diylbis[bis(4-methylphenyl)phosphine] In dichloromethane for 0.5h; Inert atmosphere; Stage #2: With hydrogen In dichloromethane for 1h; | 1.3 Under an argon atmosphere, a 1.0 ml of methylene chloride solution of (S)-tol-binap (3.4 mg, 0.0050 mmol) was added to a 1.0 ml of methylene chloride solution of [Rh(COD)2]BF4 (2.0 mg, 0.0050 mmol), and stirred for 30 minutes. Then, hydrogen gas was introduced into the schlenk tube, and the mixture was stirred for 1 hour. Successively, the reaction mixture was concentrated to dryness in vacuo, and 0.5 mL of methylene chloride was added thereto. To the mixture, a 1.5 ml of methylene chloride solution of hexayne compound obtained by above example 1 (2) (36.1 mg, 0.0500 mmol), then, the mixture was stirred at room temperature for 16 hours. Concentration of the reaction mixture and subsequent purification by thin-layer chromatography (ethyl acetate/methanol=20/1) gave 16.6 mg of the target material as a colorless solid in a yield of 46%. The optical purity of the obtained target material was 91% ee |
