Abstract
A new cembradiene diterpenoid 1, together with the known antiplasmodial cembradiene 2, was isolated from the sea whip Eunicea sp. collected from Santa Marta Bay on the Colombian Caribbean sea. The structures and absolute stereochemistry of 1-2 were determined by extensive spectroscopic analysis, chemical transformation of 2 to the new diterpenoid 3, and by using modified Mosher's method. This is the first known report regarding the determination of the absolute configuration of 2.
