Some ester derivatives of salonitenolide have been prepared from cnicin, a germacranolide sesquiterpenoid. The compounds were tested for their antibacterial activity. The 8,15-diesters showed a good activity, comparable with that of cnicin. The 15-mo

The acid-catalyzed cyclization of mono epoxides of cnicin acetonide (3) was investigated. Several 6,12-eudesmanolides were obtained, and their stereochemistry established by extensive spectroscopic analyses. Chemical correlations also led to the assi
