Steps:
20 Synthesis of Example 20
According to the general operating procedures, 1,4-dihydronaphthalene (1t) (130.1 mg, 1.0 mmol) is used as a raw material, 0.50 mol% nickel bromide (1.1 mg, 0.005 mmol) is used as a catalyst, and 0.60 mol% 6,6'- Dimethyl-2,2'-bipyridine (1.0 mg, 0.006 mmol) is the ligand, manganese powder (16.5 mg, 0.30 mmol, 0.30 equiv) is the reducing agent, and diethyl phosphite (30.0 mg, 0.20 mmol, 0.20equiv) was a hydrogen source, and anhydrous chloroform (1.0 mL) was used as a solvent for the reaction.The reaction system was stirred at 35 ° C. for 24 hours. A colorless oil (99.5 mg) was obtained by silica gel column chromatography (n-hexane) with an isolated yield of 76%
