A process which can afford a large quantity of the title compound was explored by modifying the Horton’s original route. The developed process features highly stereoselective reduction of the oxime with sodium dihydrobis(2-methoxyethanolato)aluminate(1-) and efficient dehydrobromination with 1,8-diazabicyclo[5.4.0]undec-7-ene.
通过修改霍顿的原始路线,探索了一种可以大量生产标题化合物的工艺。该工艺的特点是,使用二氢双(2-甲氧基乙醇酸)铝酸钠(1-)对肟进行高度立体选择性还原,并使用1,8-二氮杂双环[5.4.0]十一碳-7-烯进行高效脱氢溴化。
