Three new sesquiterpenoids (pestaloporonins A-C; 1-3) related to the caryophyllene-derived punctaporonins were isolated from cultures of a fungicolous isolate of Pestalotiopsis sp. The structures of 1-3 were determined by analysis of NMR and HRMS data, and the structure of 1, including its absolute configuration, was confirmed by X-ray crystallographic analysis. Compounds 1 and 2 contain new bicyclic and tricyclic ring systems, respectively.
从拟盘多毛孢属（Pestalotiopsis sp.）的一种真菌寄生分离物的培养物中，分离出了三种与石竹烯衍生的punctaporonins相关的新倍半萜（pestaloporonins A-C；1-3）。通过对核磁共振（NMR）和高分辨率质谱（HRMS）数据的分析确定了1-3的结构，并且通过X射线晶体学分析证实了1的结构，包括其绝对构型。化合物1和2分别包含新的双环和三环环系。
