Solenopsin synthesis
WebJul 17, 1998 · The enantioselective synthesis of the trans-2,6-dialkylpiperidine alkaloids (2R,6R)-lupetidine and (2R,6R)-solenopsin A from 6-methyl-2-piperidone 1 is described. The key step of this synthesis consists of the addition of a dialkylcopper derivative to the thioimidate salt 3 followed by sodium borohydride reduction of the resulting iminium salt.

WebOct 15, 2008 · We reasoned that elastase B production might be less dependent on rhl QS signaling than pyocyanin synthesis. Hence, to support our rationale, we used a ΔrhlI mutant strain, PDO 100, in an elastase B assay and showed that 50 µmol/L solenopsin indeed suppressed elastase B production as efficiently as a genetically impaired mutant.
