摘要
Due to their complex and diverse structures and significant bioactivities, the chemical synthesis of the akuammiline alkaloids has been highly pursued in the chemical community. Strictamine, as one of the representative members in this natural product family, is structurally featured by a cage like methanoquinolizidine framework and an all. carbon quaternary stereogenic center at C7, posing a great challenge in synthesis. Pursuit in the total synthesis of strictamine has a history of over four decades; however, the breakthroughs came until the recent two years. This review briefly summarizes the three total syntheses and four formal syntheses of strictamine that have been reported since 2016, by highlighting the key strategies and reactions employed in each of the synthesis. Moreover, perspectives in this research field have also been suggested at the end of this review.
