Embodiment 1
[0046] Embodiment 1: 1 synthesis of compound
[0047]
[0048] Step1. Add 100mmol formyl chloride to anhydrous THF, add a THF solution of phenylmagnesium bromide dropwise, and react the mixture at room temperature for 2h. Ice water was added, stirred, and the reaction solution was extracted with dichloromethane and dried. The obtained crude product was subjected to column chromatography to obtain 80 mmol of product 1-1. Yield 80%
[0049] Step2. Under the protection of nitrogen, 96mmol of triphenylphosphine bromide was dissolved by adding an appropriate amount of anhydrous THF, then cooled to 0°C, and 1.2 equivalents of potassium tert-butoxide was added, and the reaction was kept for 1 hour, and 1-1 80mmol was quickly added dropwise. The THF solution was slowly warmed to room temperature and reacted overnight. After the reaction was completed, most of the reaction solution was concentrated, then passed through a thin Celite column, and continued to concentrate to dryness...
