Three new monotetrahydrofuran (mono-THF) acetogenins, anmontanins A-C (1-3) were isolated from the leaves of Annona montana. Anmontanin C (3) is the first stereochemically pure acetogenin reported to have a gamma-hydroxymethyl-gamma-lactone moiety. Two known mono-THF acetogenins, murisolin and annonacin, were isolated from the seeds of the plant. The structures of compounds 1-3 were elucidated by spectral methods and chemical derivatization.
