The first asymmetric synthesis of the ant venom alkaloid (3S,5S,8aR)-3-butyl-5-(4-pentenyl)indolizidine (1) has been performed by starting with the Sharpless asymmetric dihydroxylation of N- alkenylcarbamate (3) followed by reductive annulation (5-exotetr

An intramolecular amidomercuration of α-butylated 4-pentenylcarbamate 5 predominantly provided trans-2,5-disubstituted pyrrolidine 6, which was elaborated to chiral trans-5-butyl-2-alkylpyrrolidines 10 and 13, constituents of ant venoms.
