3-氟-5-碘苄醇

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

实验步骤: (3-fluoro-5-iodophenyl)methanol (9.79 g, 35.0 mmol) was dissolved in DCM (94 mL) and then silica gel (18.0 g) was added. To the mixture at room temperature was added PCC (18.3 g, 45.0 mmol) portion-wise and the mixture agitated at room temperature for 1 h and followed by TLC. After 1 h, TLC indicated complete conversion of the SM to a non-polar (presumably aldehyde). The reaction mixture was filtered over 1-inch plug of silica pad and eluted with 30% Ether in DCM (200 mL). The filtrate was concentrated in vacuo to afford the crude product, which was taken to the next step without further purification. silica gel (18.0 g) was added After 1 h The reaction mixture was filtered over 1-inch plug of silica pad eluted with 30% Ether in DCM (200 mL) The filtrate was concentrated in vacuo

实验步骤: Methyl 3-fluoro-5-iodobenzoate (5.49 g, 19.60 mmol) was dissolved in DCM (100 mL) and cooled to −78° C. DIBAL-H (49.0 mL, 49.0 mmol) was added dropwise over 30 min and then after 1 h another portion of DIBAL-H (49.0 mL, 49.0 mmol) was added. Reaction mixture agitated at −78° C. for 4 h and poured carefully onto ice-cold 1N HCl. The mixture was agitated for 10 min and the layers separated and the aq. layer extracted with DCM and the combined organic extract was dried (magnesium sulfate), filtered and concentrated in vacuo to afford the desired product in quantitative yield. LCMS not conclusive. Reaction mixture poured carefully onto ice-cold 1N HCl The mixture was agitated for 10 min the layers separated the aq. layer extracted with DCM the combined organic extract was dried (magnesium sulfate) filtered concentrated in vacuo
