4-Hydroxy-3-(3′-methyl-2′-butenyl)-benzoic acid, 4-hydroxy-3-(3′-methyl-3′-buten-1′-inyl)-benzoic acid, 2-isopropenylbenzofuran-5-carboxylic acid, anofinic acid, and its 3,4- trans -dihydroxy derivative were isolated from the fungus Curvularia fallax . Biotransformation with p -amino-benzoic acid led to the corresponding 3-prenylbenzoic acid while 2,4-dihydroxybenzoic acid was alkylated in 5-position. Other
摘要 4-Hydroxy-3-(3'-methyl-2'-butenyl)-benzoic acid, 4-hydroxy-3-(3'-methyl-3'-buten-1'-inyl)-benzoic acid, 2-从真菌 Curvularia fallax 中分离出异丙烯基苯并呋喃-5-羧酸、anofinic 酸及其 3,4-反式二羟基衍生物。用对氨基苯甲酸进行生物转化得到相应的 3-异戊二烯苯甲酸,而 2,4-二羟基苯甲酸在 5 位被烷基化。其他相关底物没有被微生物异戊二烯化。比较了这些化合物在 C.fallax 和 Streptomyces niveus 中的生物合成。
