An efficient flow process for the selective hydroboration and oxidation of different alkenes using 9-borabicyclo(3.3.1)nonane (9-BBN) allows facile conversion in high productivity (1.4 g h ) of amorpha-4,11-diene to the corresponding alcohol, which is an advanced intermediate in the synthesis of the antimalarial drug artemisinin. The in situ reaction of borane and 1,5-cyclooctadiene using a simple flow generator proved to be a cost efficient solution for the generation of 9-BBN.
一种高效的流程工艺,使用 9-硼双环[3.3.1]壬烷(9-BBN)选择性地对不同烯烃进行硼氢化和氧化,可轻松将高产量(1.4 g/h)的法呢烯-4,11-二烯转化为相应的醇,这是合成抗疟药物青蒿素的重要中间体。使用简单的流动发生器,硼烷和 1,5-环辛二烯的原位反应被证明是生成 9-BBN 的一种具有成本效益的解决方案。
