A protective group free, concise, and stereoselective totalsynthesis of (+)-artemisinin, starting from readily available (R)-(+)-citronellal, is described. Asymmetric 1, 4-addition, Aldol condensation, Ene reaction, regioselective hydroboration are the key steps involved in the totalsynthesis of the target molecule.

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
使用9-硼环环(3.3.1)壬烷(9-BBN)进行选择性氢硼化和氧化不同烯烃的有效流程,可以轻松地以高生产率(1.4 g h -1)的无定形4,11-二烯转化为苯相应的醇,它是抗疟药青蒿素合成中的高级中间体。硼烷和1,5-环辛二烯的原位反应使用简单的流发生器证明是生成9-BBN的经济高效的解决方案。
