8-Lanosten-24-one was converted into 8-lanosten-23-one by carbonyl transposition via 23,23-dimethoxy-8-lanosten-24-one without degradation and reconstruction of the side chain. By the same procedure 29-nor-9(11)-lanosten-24-one was transformed into the corresponding 23-one.
8-lanosten-24-one 通过羰基转座通过 23,23-dimethoxy-8-lanosten-24-one 转化为 8-lanosten-23-one,侧链没有降解和重构。通过相同的程序,29-nor-9(11)-lanosten-24-one 被转化为相应的 23-one。
