制备方法与用途

生产方法

在2L四口瓶中加入105mL(86g,1mol)3-甲基-2-丁酮和600mL无水甲醇,搅拌冷却至0~5℃的冰盐浴。然后快速将160g(54.6mL,1mol)溴从滴液漏斗中加入,此过程需迅速完成以避免异构体增多,温度会短暂升高但不可超过10℃。继续在10℃搅拌至反应结束,直至红色完全消失(约需45分钟),然后加300mL水(不应分层)。室温下搅拌过夜让缩酮充分水解,再加入900mL水,用乙醚500mL×4萃取,合并醚液。依次用10%的碳酸钾溶液200mL和水200mL×2洗涤,然后用无水氯化钙干燥1小时。减压旋转蒸发除去溶剂,得到粗产物约145~158g(主产物∶异构体比例约为95∶5)。通过V氏柱减压分馏收集83~86℃/7.2kPa的馏分,最终获得产品115~128g,收率在69.5%~77.5%,其1-溴物纯度达到95%。
