Solenopsin synthesis
 solenopsin A - ResearchGate)
The total synthesis of solenopsin has been described by several methods. A proposed method of synthesis (Figure 1) starts with alkylation of 4-chloropyridine with a Grignard reagent derived from 1-bromoundecane, followed by reaction with phenyl chloroformate to form 4-chloro-1-(phenoxycarbonyl)-2-n … See more Solenopsin is a lipophilic alkaloid with the molecular formula C17H35N found in the venom of fire ants (Solenopsis). It is considered the primary toxin in the venom and may be the component responsible for the See more Solenopsins are described as toxic against vertebrates and invertebrates. For example, the compound known as isosolenopsin A has been demonstrated to have strong insecticidal effects which may play a central role in the biology of fire ants.
