具体实施方式
本发明反应式如下:
实施例:
第一步:将化合物 1 (330 g, 1.77 mol)溶于乙醇 (2000 mL) 中,然后0℃加入硼氢化钠(67.3 g, 1.77 mol), 然后0℃反应2小时,TLC (石油醚/乙酸乙酯体积比 = 5/1) 显示反应完毕。将200 mL H2O倒入反应液中,然后旋出乙醇。水相用600 mL乙酸乙酯萃取3次。有机相用Na2SO4干燥后减压浓缩得到粗品化合物2,直接用于下一步。
第二步:将化合物2(267 g,1.43 mol)溶于无水四氢呋喃(1500 mL),然后在0℃下分批次缓慢加入PPh3(408 g,1.56 mol)和DIAD(315 g,1.56mol)。然后反应液在25℃下反应16小时。然后将反应液减压浓缩得到的粗品用硅胶柱色谱纯化(梯度洗脱:石油醚/乙酸乙酯体积比 = 100/1~50/1~30/1),从而得到油状的纯品化合物3(223 g),收率:28%。
第三步:将化合物3(100 g,588.2 mmol)溶于二氯甲烷(1000 mL)中,然后在0℃下分批次缓慢滴加三氟醋酸(3.35 g,29.41 mmol)和N-甲氧基甲基-N-(三甲基硅甲基)苄胺(167.8 g,705.8 mol)的二氯甲烷(200 mL)溶液。然后在16℃反应4小时。TLC (石油醚/乙酸乙酯体积比 = 5/1) 显示反应完毕。反应液用NaHCO3水溶液调pH=8,然后用300 mL二氯甲烷萃取3次。有机相用Na2SO4干燥,过滤,滤液浓缩得到的粗品用石油醚重结晶得到白色固体化合物4(120 g,67.4%)。
第四步:将化合物4(150 g,0.495 mol)溶于无水甲醇(1000 mL)中,然后在0℃缓慢滴加氯化亚砜(204 g,1.73 mol)。然后反应液在70℃反应10小时。TLC (石油醚/乙酸乙酯体积比 = 5/1) 显示反应完毕。反应液用Na2CO3水溶液调pH=8,然后用600 mL二氯甲烷萃取4次。有机相用Na2SO4干燥,过滤,滤液浓缩得到黄色油状化合物5(125 g),收率:96.9%。
第五步:将化合物5溶于甲醇中,然后加入氢氧化钯和Boc酸酐。反应液在50 psi的氢气压力下于40℃反应10小时。反应液过滤,滤液浓缩得到的粗品用硅胶柱色谱纯化从而得到黄色油状的纯品化合物6(49 g),收率:94%。
