Abstract The alkaloidal venom components of two species of thief ants,Solenopsis (Diplorhoptrum) species AA andS. (Diplorhoptrum)conjurata have been found to contain (5Z,9Z)-3-hexyl-5-methylindolizidine and a mixture of (5Z,9Z)-3-ethyl-5-methylindolizidine andcis-2-methyl-6-nonyl-piperidine,trans-2-methyl-6-nonylpiperidine,cis-2-methyl-6-undecylpiperidine, and hexadecanoic acid.Monomorium pharaonis was similarly investigated and found to contain the indolizidine and pyrrolidines previously described (Ritter et al., 1977b). Both indolizidines were synthesized along with their stereoisomers and separated by preparative gas chromatography. Spectral studies revealed the stereochemistry to be 5Z,9Z in both cases. The stereochemistry of 2-butyl-5-pentylpyrrolidine inM. phaeronis has also been established. Biosynthetic relationships are discussed.
