General procedure: To the chloro compounds (1.00 mmol) in toluene, were added piperazines 8a-j (1.0 mmol) at room temperature. The reaction mixture was heated at 110 oC for overnight. After completion (TLC), the reaction mixture was extracted with ethyl acetate and water. The organic layer was separated and dried over anhydrous Na2SO4, evaporated to dryness. The residue was purified with column chromatography using an eluent of 25% ethyl acetate in hexane to furnish the compounds with moderate to good yields (64-82%)., 30459-17-7

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.30459-17-7,1-(4-Trifluoromethylphenyl)piperazine,as a common compound, the synthetic route is as follows.

General procedure: At first, THF (2.0 mL) was added to a mixture of oxabenzonorbornadiene 1 (0.347 mmol, 1.0 equiv), amine 4 or 6 (1.041 mmol, 3.0 equiv), NaI (10.34 mg, 0.069 mmol, 0.2 equiv), ligand L2 (4.5 mg, 0.0167 mmol, 4.8 mol %) and [Rh(C2H4)2Cl]2 (2.7 mg, 0.0069 mmol, 2.0 mol %) under N2. The mixture was then stirred at RT for 1 h and heated at reflux for 6-12 h after which the residue was subjected directly to silica gel column chromatography [ethylacetate/hexanes (1:1-2:1 v/v) as the eluent] to afford the desired alcohol product 5 or 7. The enantioselectivity was determined by chiral HPLC on a chiralcel OD-H, chiralcel AD-H, or Lux Amylose-2 column.

Example 7 [0116] 0.61 g (1.29 mmol) of betulonic acid chloride was dissolved in 40 mL of anhydrous dichloromethane (CH2Cl2), and then 0.72 mL (5.16 mmol) of anhydrous triethylamine and 0.60 g (2.58 mmol) of 1-(4-trifluoromethylphenyl)piperazine were added thereto, and then stirred at 25 C. for 48 hours. The resulting product was washed with 10% HCl (40 mL¡Á3), further washed with pure water (40 mL¡Á3), and then a solvent layer was dried by 10 g of anhydrous Na2SO4. A dichloromethane (DCM) layer was evaporated and dried to obtain 0.85 g of light brown solids. These light brown solids were dissolved in ethanol to prepare a sample, and then this sample was fractionated by RP C18 semi-prep HPLC, and then completely evaporated and dried to obtain 0.64 g (yield: 74.9%) of 4-(4?-trifluoromethylphenylpiperazine-1-yl) amide betulonic acid.
