5. Novel alkaloids from the poison glands of ants Leptothoracini

Article abstract of DOI:10.1002/hlca.19950780107

Novel pyrrolidine alkaloids were isolated from the poison glands of ants Leptothoracini (Myrmicinae) and identified as a mixture of N-alkylated 3-methylpyrrolidines. The females of these species produce male-attracting pheromones in their poison glands. The basic compounds in the secretions were found to be active. The major alkaloid, 3-methyl-1-(3-methylbutyl)pyrrolidine (5), is present in only ng quantities per gland.
