螺佐呋酮制备

方法l：在室温和搅拌下，将5-乙酰基-2-羟基苯甲酸甲酯(8.0mol)加到1.32kg碳酸钾在2.0L二甲基甲酰胺的悬浮中。在60℃加热1h后，在5℃和3h内加入1.32kgα-溴-γ-丁内酯。加毕在45℃下搅拌10h。冷却，过滤除去不溶的无机物。滤液减压浓缩，剩余物真空蒸馏以移去没有反应的5-乙酰基-2-羟基苯甲酸甲酯。剩余物(粗品化合物(I)，用甲醇重结晶后，熔点112～113℃)溶于2L甲醇和2L 50%氢氧化钠水溶液。并于60℃加热。冷却后，将反应液倾入1.5L冰水，用2.2L浓盐酸酸化。过滤收集析出的沉淀，水洗，干燥。溶于1L二氧六烷和1L甲苯。加入400g对甲苯磺酸，在装有分水器的装置中加热回流8.5h。减压浓缩，剩余物倾入10L冰水。过滤收集析出的沉淀，水洗，干燥，溶于乙酸乙酯。干燥后浓缩，用丙酮-甲醇重结晶，得化合物(Ⅱ)，总收率45%，熔点155～158℃。
1.26mol化合物(Ⅱ)在2.8L乙酸酐的溶液和560ml三乙胺加热回流。减压浓缩，剩余物倾人3L冰水。过滤收集析出的沉淀，洗涤后，用甲醇重结晶，得化合物(Ⅲ)，收率55%，熔点132～134℃。
7.4mol化合物(Ⅲ)和94g氯化钠溶于1.5L二甲亚砜，在150℃下搅拌1.5h。冷却后，倾入冰水。过滤收集析出的沉淀，水洗，干燥，用乙醇重结晶，得螺佐呋酮，收率88%，熔点。102～104℃。
从化合物(I)也可直接得到化合物(Ⅲ)。化合物(I)(4.7mmol)在15ml乙酸酐的溶液和3ml三乙胺加热回流10h。减压浓缩，剩余物倾入冰水，用乙酸乙酯提取。提取液水洗，干燥，减压浓缩。剩余物用硅胶层析，四氯化碳-丙酮(5：1，体积比)洗脱。收集第二组分洗脱液，用甲醇重结晶，得化合物(Ⅲ)，收率47%。
方法2：一步合成法。以5-乙酰基-2-[(四氢-2-氧-3-呋喃基)氧]苯甲酸甲酯(化合物(I))为原料，可一步反应得到螺佐呋酮，但对试剂要求较高。
将4.17g1，5-二氮双环[5．4．0]十一烯-5(DBU)和67g氯化钠溶于1L二甲基甲酰胺，在150℃和搅拌下，于2h内滴加5-乙酰基-2-[(四氢-2-氧-3-呋喃基)氧]苯甲酸甲酯(278g，lmo1)在1.8L二甲基甲酰胺的溶液，加毕再搅拌2h。减压蒸去溶剂，剩余物用水稀释后，用二氯甲烷提取。提取液洗涤，干燥，通过硅胶进行脱色。二氯甲烷溶液减压浓缩，产生的结晶再用乙醇重结晶，得136g螺佐呋酮，收率67%，熔点106-107℃。
