The structure of the sesquiterpene lactone repin

  • Published:
Chemistry of Natural Compounds Aims and scope

Summary

1. Three sesquiterpene lactones have been isolated fromCentaurea hyrcanica: repin, acroptilin, and a new lactone related to them with mp 218–220°C (ethanol), [α] 20D + 104.7° (c 1.91; dioxane).

2. Structure (I) has been proposed for repin on the basis of the reactions performed, of an interpretation of the NMR spectra of compounds (I-XII) using the INDOR method, and also of a study of NMR spectra with additions of a paramagnetic salt.
