Synthesis and structure elucidation of open-chained putrescine-bisamides from Aglaia species
Detterbeck, Richard,Hesse, Manfred
, p. 6887 - 6893 (2007/10/03)
The structures of the eight recently described open-chained putrescine bisamide alkaloids secoodorine (1), aglaithioduline (3), aglaiduline (4), aglaidithioduline (5), grandiamide B (13), grandiamide C (14), pyramidatine (20), and secopiriferine (22), which were isolated from different Aglaia species, have been verified by synthesis. In addition to that, the published structure 2 for hemileptagline had to be revised, and for secoodorine (1) the absolute configuration could be established.
