The monoglyceryl ester (1) of a new halimane diterpenoic acid has been isolated as diacetyl derivative (2) from the mantle tissue of the Antarctic nudibranch Austrodoris kerguelenensis. The structure and the relative stereochemistry have been established by means of spectroscopic and chemical methods and by comparison with model compounds. An analysis of conflicting NMR data reported in literature for molecules related to the diterpenoic part of 1 has also been made.

Abstract
The monoglyceryl ester (1) of a new halimane diterpenoic acid has been isolated as diacetyl derivative (2) from the mantle tissue of the Antarctic nudibranch Austrodoris kerguelenensis. The structure and the relative stereochemistry have been established by means of spectroscopic and chemical methods and by comparison with model compounds. An analysis of conflicting NMR data reported in literature for molecules related to the diterpenoic part of 1 has also been made.File in questo prodotto:
