The absolute configuration of the diterpenoid 9,12-cyclomulin-13-ol (1), a constituent of Azorella and Laretia species, has been established by vibrational circular dichroism spectroscopy in combination with density functional theory calculations. The obtained normal diterpene absolute configuration confirms that of azorellanol (2), which was determined by single crystal X-ray diffraction.
二萜类化合物9,12-环穆林-13-醇（1）是亚佐雷拉属和拉雷蒂亚属植物的一种成分，其绝对构型已通过振动圆二色光谱结合密度泛函理论计算得以确定。所获得的正常二萜绝对构型与通过单晶X射线衍射确定的氮杂环丁醇（2）的构型一致。
