Several rearrangements of 17-mesyloxy and 12,17-dimesyloxy derivatives of ent-beyer-15-enes were carried out. Rearrangement processes mainly occurred with the participation of the functional group at C-12, although the group at C-17 and the C-15/C-16 double bond aided in an observed 16(13) → 12/11(12) → 13 double rearrangement. The influence of the groups at C-12 and their stereochemistry, of the mesyloxy
进行了对-beyer-15-烯的17-甲氧基和12,17-二甲氧基衍生物的几种重排。重排过程主要发生在C-12的官能团的参与下,尽管在观察到的16(13)→12/11(12)→中C-17和C-15 / C-16双键的基团13双重重排。研究了在C-12上的基团及其立体化学,在C-17上的甲磺酰氧基以及C-15 / C-16双键的影响,并讨论了观察到的重排过程的立体化学。
