12,13-Difluorofarnesyl diphosphate, prepared using Suzuki–Miyaura chemistry, is a potent inhibitor of aristolochene synthase (AS), indicating that the initial cyclisation during AS catalysis generates germacryl cation in a concerted reaction.
使用 Suzuki-Miyaura 化学制备的 12,13-二氟法呢基二磷酸盐是马兜铃烯合酶 (AS) 的有效抑制剂,表明 AS 催化过程中的初始环化在协同反应中生成甲丙烯酸阳离子。

enzyme aristolochene synthase from Penicillium roqueforti (PR-AS) has been probed with the farnesyldiphosphateanalogues 6- and 14-fluoro farnesyldiphosphate (1b and 1c). Incubation of these analogues with PR-AS followed by analysis of the reaction products by GC-MS and NMR spectroscopy indicated that these synthetic FPP analogues were converted to the fluorinated germacrene A analogues 3b and 3c, respectively
