苯基-D5-硼酸

反应条件: temp:100.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of compound A (57 g) in tetrahydrofuran (600 mL) was added triethylamine (30 mL) dropwise over 30 min. The reaction mixture was kept at room temperature for 3 hours. The precipitated solid was filtered and the filtrate was concentrated in vacuo. The residue was reprecipitated from diethyl ether to afford compound B (31 g) as a yellow solid. To a solution of compound phenyl-d5-boronic acid (25 g) in 1,4-dioxane/water (900 mL/90 mL) was added [Rh(ndb)2]BF4 (1.3 g), racemic BINAP (2.1 g) and triethylamine (14 mL), then the reaction mixture was kept at room temperature for 2 hours under N2. Then compound indenone (19 g) was added, and the resulting mixture was heated to 100° C. for 3 hours. The precipitated solid was filtered off. The filtrate was concentrated in vacuo. The residue was purified by chromatography to afford indanone C (10 g). The precipitated solid was filtered off The filtrate was concentrated in vacuo The residue was purified by chromatography
