  • Title: Formal Total Synthesis of (±)-Strictamine by [2,3]-Sigmatropic Stevens Rearrangements.
    Author: Eckermann R, Breunig M, Gaich T.
    Journal: Chemistry; 2017 Mar 17; 23(16):3938-3949. PubMed ID: 28071823.
    Abstract:
    To date, more than 100 congeners of the akuammiline alkaloid family have been isolated. Their signature structural element is a methanoquinolizidine moiety, a cage-like scaffold structurally related to adamantane. The structural variations of the family members originate from oxidative processes that mostly trigger rearrangements of the methanoquinolizidine motif. The family of the akuammiline alkaloids is best represented by strictamine. It bears the least functionalized carbon skeleton of all family members without lacking the signature structural motifs. Herein, we report the formal synthesis of strictamine through a Stevens [2,3]-sigmatropic rearrangement as a key step and the synthetic pitfalls related with its synthesis.
