摘要：

An asymmetric total synthesis of the akuammiline alkaloid (+)-strictamine is described. The key steps of the synthetic route involve an improved Johnson-Claisen rearrangement to facilitate the formation of the challenging C15-C20 linkage and the (E)-alkene side chain, intramolecular nucleophilic substitution cyclization to establish the E ring and diastereoselective Brown hydroboration of the terminal alkene to introduce the C16 stereocenter.
