YieldReaction ConditionsOperation in experiment
98% Example 8; Preparation of Haloorganic Compound for Use in Total Synthesis of Ratanhine; Haloorganic compound 15 was synthesized by a multi-step process. To a mixture of methyltriphenylphosphonium bromide (14.08 g, 39.4 mmol) in toluene at 23 C. was added a solution of potassium tert-butoxide (4.47 g, 39.8 mmol) in THF (60 mL) dropwise via cannula, and the resulting mixture was allowed to stir at 23 C. for 4 hours. The resulting yellow mixture was cooled to -78 C. and a solution of 4-iodo-salicylaldehyde (4.35 g, 17.5 mmol) in toluene (40 mL) was added dropwise via cannula. The resulting mixture was allowed to slowly warm to 23 C. and was stirred at that temperature for 12 hours. The reaction was then quenched with the addition of saturated aq. ammonium chloride (100 mL). The resulting mixture was then diluted with water (200 mL) and extracted with Et2O (3×100 mL). The combined organic fractions were then washed with brine (100 mL), dried over magnesium sulfate, and concentrated in vacuo. Purification by flash chromatography (SiO2, hexanes:ethyl acetate 7:1?1:1) yielded 2-hydroxy-5-iodostyrene as a colorless solid (4.0 g, 98%). See also Gligorich, K. M., 2006.
