  • Title: Daphhimalenine A, a new alkaloid with an unprecedented skeleton, from Daphniphyllum himalense.
    Author: Zhang Y, Di YT, Zhang Q, Mu SZ, Tan CJ, Fang X, He HP, Li SL, Hao XJ.
    Journal: Org Lett; 2009 Dec 03; 11(23):5414-7. PubMed ID: 19904981.
    Abstract:
    Daphhimalenine A (1), a novel alkaloid with a rearrangement C-21 skeleton, containing a unique 1-azabicyclo[5.2.1]decane ring system, was isolated from the leaves of Daphniphyllum himalense, along with biogenetically related alkaloids daphhimalenine B (2) and daphnezomine T. Their structures were established on the basis of spectroscopic data, and the absolute configuration of 1 was assigned by computational methods. A plausible biosynthetic pathway of 1 was also proposed.
