8-环丙基-2,2-二甲基-3,4-二氢色烯-6-甲醛

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

实验步骤: A vial was charged with Pd(OAc)2 (7.99 mg, 0.04 mmol), XPhos (25.5 mg, 0.05 mmol), potassium carbonate (148 mg, 1.07 mmol), potassium cyclopropyltrifluoroborate (58.0 mg, 0.39 mmol) and 8-chloro-2,2-dimethyl-3,4-dihydro-2H-chromene-6-carbaldehyde (80 mg, 0.36 mmol). The mixture was dissolved in cyclopropylmethyl ether (1.62 mL) and water (0.16 mL) and purged with Ar. The reaction mixture was then stirred at 100° C. overnight, cooled to room temperature and filtered through a pad of celite. The filtrate was concentrated under vacuum, and the crude residue was purified by silica gel chromatography eluting with 0-20% EtOAc/hexanes to afford the desired product as a pale-yellow oil. water (0.16 mL) and purged with Ar cooled to room temperature filtered through a pad of celite The filtrate was concentrated under vacuum the crude residue was purified by silica gel chromatography eluting with 0-20% EtOAc/hexanes
