5-溴-1-亚甲基-2,3-二氢-1H-茚

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

实验步骤: The title compound was synthesized in analogy to example S87 using diethyl zinc (3.25 ml, 1M solution in hexane, 3.25 mmol), trifluoroacetic acid (251 μl, 3.25 mmol), CH2I2 (262 μl, 3.25 mmol) and 5-bromo-1-methyleneindan (340 mg, 1.63 mmol). The isolated residue was purified by flash column chromatography (100% pentane) to give 5′-bromo-2′,3′dihydro-spiro[cyclopropane1,1′-[1H]indene](345 mg, 95%) as a colorless oil. 1H NMR (CDCl3, 300 MHz): δ 7.40-7.29 (m, 3H), 3.02 (apt t, J=7.5 Hz, 2H), 2.11 (apt t, J=7.5 Hz, 2H), 0.96-0.84 (m, 4H). The isolated residue was purified by flash column chromatography (100% pentane)

实验步骤: The title compound was synthesized in analogy to example S87 using triphenyl-phospho-nium bromide (1.49 g, 4.17 mmol), n-BuLi (3.26 ml, 1.6M solution in hexane, 5.21 mmol) and 5-bromo-1-indanone (880 mg, 4.17 mmol) in DMSO (10 ml). The residue which was isolated was purified by filtration through a short pad of silica using pentane as eluant to give 5-bromo-1-methylene-indan (510 mg, 59%) as a colorless oil. 1H NMR (CDCl3, 300 MHz): δ 7.40-7.29 (m, 3H), 5.44 (m, 1H), 5.05 (m, 1H), 2.98-2.94 (m, 2H), 2.83-2.78 (m, 2H).
