1070663-78-3, Dicyclohexyl(2′,4′,6′-triisopropyl-3,6-dimethoxy-[1,1′-biphenyl]-2-yl)phosphine is a chiral-phosphine-ligands compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Example 0848 A mixture of 2-chloro-7-(1,3-dimethyl-1H-pyrazol-4-yl)-1,5-naphthyridine (20 mg), 3-isopropylisoxazole-5-amine (10 mg), tris(dibenzylideneacetone)dipalladium(0) (4 mg), 2-(dicyclohexylphosphino)-3,6-dimethoxy-2′,4′,6′-triisopropyl-1,1′-biphenyl (4 mg), sodium tert-butoxide (11 mg), and 1,4-dioxane (0.6 mL) was stirred at 140 C. for 30 minutes using a microwave reaction apparatus. The reaction mixture was cooled to room temperature, the insolubles were filtered off, and the solvent was distilled off under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate-methanol, chloroform-methanol, NH silica), thereby obtaining N-(7-(1,3-dimethyl-1H-pyrazol-4-yl)-1,5-naphthyridin-2-yl)-3-isopropylisoxazole-5-amine (0.8 mg) as a pale yellow solid. 1H-NMR (DMSO-d6) delta: 8.88 (1H, d, J=2.0 Hz), 8.22 (3H, d, J=9.9 Hz), 7.31 (1H, d, J=8.6 Hz), 6.70 (1H, s), 6.55 (1H, s), 3.85 (3H, s), 3.03-2.94 (1H, m), 2.43 (3H, s), 1.29 (6H, d, J=6.6 Hz). MS m/z (M+H): 349.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1070663-78-3,Dicyclohexyl(2′,4′,6′-triisopropyl-3,6-dimethoxy-[1,1′-biphenyl]-2-yl)phosphine,as a common compound, the synthetic route is as follows.

General procedure: In a nitrogen-filled glovebox, phosphine ligand (0.21 mmol,1.00 eq.) and [(1,5-cyclooctadiene) Pd(CH2TMS)2] (80 mg,0.21 mmol, 1.00 eq.) were suspended in pentane (5.0 mL). The reaction mixture was stirred vigorously at room temperature, duringwhich time a solid precipitated from solution. After 48 h, thenon-homogenous mixture was filtered though a sintered glass frit.The filter cake was washed with pentane (10.0 mL) to yield thedesired complex. 9: Yellow-green solid (Yield: 106 mg, 79%). IR (neat): 2931,2850, 1580, 1456, 1419, 1376, 1359, 1293, 1252, 1170, 1155,1087, 1044, 1013, 929, 870, 851, 798, 746, 715 cm1.
