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−1) 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. An efficient and scalable flow protocol for the selective hydroboration–oxidation of terminal alkenes enabled easy access to dihydroartemisinic alcohol, an advanced intermediate in the synthesis of the antimalarial drug artemisinin.
