As a common heterocyclic compound, it belongs to quinuclidine compound,Quinuclidine-4-carboxylic acid hydrochloride,40117-63-3,Molecular formula: C8H14ClNO125,mainly used in chemical industry, its synthesis route is as follows.

To a solution of Example 246A (48 mg, 0.11 mmol) and Example 246B (25 mg, 0.11 mmol) in EtOH (1 mL) and toluene (1 mL) under an argon atmosphere were added 2M Na2CO3 (0.165 mL, 0.33 mmol) followed by Pd(PPh3)4 (13 mg, 0.011 mmol)). The resulting suspension was stirred under argon at 85¡ã C. for 2 hours. The reaction was cooled to ambient temperature, concentrated and purified by preparative HPLC to give the title compound (8.8 mg). HPLC Rt=2.203 min. m/z=446.08.

With the complex challenges of chemical substances, we look forward to future research findings about [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II),belong catalyst-palladium compound

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.72287-26-4,[1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II),as a common compound, the synthetic route is as follows.

c) N1-[2-phenyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-phenyl]-1-benzenesulfonamide. A mixture of the N1-(4-bromo-2-phenylbenzene)-1-benzenesulfonamide (0.388 g, 1.00 mmol), bis(pinacolato)diboron (0.305 g, 1.20 mmol), potassium acetate (0.294 g, 3.00 mmol) and [1,1′-bis(diphenylphosphino) ferrocene]dichloropalladium(II) (25 mg, 0.030 mmol) in DMF (10 ml) was heated under an atmosphere of nitrogen at 100¡ã C. for 16.5 hours. The DMF was evaporated in vacuo and the residue purified by silica gel flash chromatography using methylene chloride/heptane 7:3 plus 2percent triethyl amine to provide N1-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-phenylbenzene]-1-benzenesulfonamide (0.135 g) as an oil. tR=23.13 min (RP-HPLC, 25-100percent acetonitrile-0.1percent TFA, 25 min); low resolution MS m/e 434 (M-H+)

The synthetic route of 72287-26-4 has been constantly updated, and we look forward to future research findings.
