Based on model studies with dispiroundecane 10, dispiroundecane 1 has been synthesized and rearranged to (±)-modhephene 6 and (±)-isocomene 7. The epimeric dispiroundecane 9 yields (±)-epimodhephene 12. A total of thirteen rearrangement products (6, 7, 12, 37, 38, 39, 42, 43, 44, 55, 57, 64, 67) have been isolated from 1 and/or 9, including six unnatural triquinanes. Two of these (55, 57) are formed
基于对双螺环烷10的模型研究,已合成了双螺环烷1并重排为(±)-对苯二酚6和(±)-异-烯7。差向异构体双螺环烷9产生(±)-环氧丙烷12。共有13个排产物(6,7,12,37,38,39,42,43,44,55,57,64,67)已经从图1和/或9中分离,包括6个非天然triquinanes。其中两个(55、57)分别由异常的1,3-和1,4-移位形成。给出了基于力场计算的机械原理。
