Synthetic Studies on Natural Diterpenoid Glyceryl Esters

Synthesis of natural bicyclic and tricyclic diterpenoid diacylglycerols has been performed by regioselective coupling of terpenoid acid with glycerol at 1′-sn position. This method may be considered a general approach to obtain optically active acylglycerols. The preparation of 13C-labelled geranylgeranoic acid glyceryl esters is also described here.
