已经使用差向异构(-)-kaur-16-en-15-ols作为模型研究了garryfoline–cuauchichicine重排的机制。研究表明,在室温下,无机酸中的15β-ol可通过15,16-氢化物移位迅速重排为16 R -(-)-kaur-15-。像veatchine一样,16α-ol在这些条件下也是稳定的。讨论了这些差向异构醇经历15,16-氢化物转变的能力的对比。
An ent-Kaurane-type diterpenoid, ent-kaurane-3,15-dione has been isolated from cell cultures of the liverwort Jungermannia subulata. Its structure was established by spectroscopic methods. (C) 1999 Elsevier Science Ltd. All rights reserved.
