The cis-1,2-dihydrocatechol 2 has been converted, via reaction sequences including Diels-Alder cycloaddition and anionic oxy-Cope rearrangement steps, into the enantiopure bicyclo[5.3.1]undecanes 20 and 33 which correspond to the AB-ring systems of ent-taxoids and taxoids, respectively.
顺式-1,2-二氢邻苯二酚 2 通过包括 Diels-Alder 环加成和阴离子氧-科普重排步骤在内的反应序列,被转化为对映体纯双环[5.3.1]十一烷 20 和 33,它们分别对应于内类脂和类脂的 AB 环系统。
