Evidence is presented showing that tetraponerine-6 2a from
Tetraponera sp. ants is biosynthesized from two molecules of
putrescine and a seven-carbon moiety coming from an eight-carbon
polyacetate chain through decarboxylation, in contrast with
tetraponerine-8 1a, which derives from one putrescine unit and a
twelve-carbon polyacetate precursor.
提供的证据表明,来自四点蚁属(Tetraponera sp.)的四点蚁碱-6(tetraponerine-6 2a)是通过去羧化反应,由两个亚精胺分子和一个来自八碳多酰化合物链的七碳部分合成的,这与四点蚁碱-8(tetraponerine-8 1a)相反,后者来源于一个亚精胺单元和一个十二碳的多酰化合物前体。
