From cultures of a Phoma species (strain S729) (Fungi imperfecti) gentisylalcohol (1), toluhydroquinone (3), and two new metabolites, gentisylacetal (2) and chlorogentisylalcohol (4), have been isolated. The structure of 2 was proven by cleavage to gentisylalcohol (1) and acetaldehyde, and by resynthesis from these moieties. The synthesis of chlorogentisylalcohol (2,5-dihydroxy-3-chloro-benzyl alcohol)
从Phoma物种的培养物中(菌株S729)(Fungi imperfecti),龙胆基醇(1),甲苯氢醌(3)和两种新的代谢产物龙胆基乙缩醛(2)和氯代龙胆醇(4)被分离出来。通过裂解成龙胆基醇(1)和乙醛,并由这些部分再合成,证明了2的结构。由氯氢醌(10)经由醛7,8合成氯gentisylalcohol(2,5-dihydroxy-3-chloro-苄基醇)(4)及其两个异构体5和6,和9分别建立了这种代谢物的结构。
