Masked talent: A tetracyclo[5.3.3.04,9.04,12]tridecane skeleton can be accessed by an intramolecular reverse‐electron‐demand Diels–Alder (REDDA) reaction of masked ortho‐benzoquinone (MOB; see scheme). This reaction gives access to the pentacyclic framework of atropurpuran, and also enables the construction of other anti‐Bredt and cage‐like complex molecules.
被掩盖的人才:可以通过被掩盖的邻苯并醌(MOB;参见方案)的分子内反电子需求Diels-Alder(REDDA)反应获得四环[5.3.3.0 4,9 .0 4,12 ]十三烷骨架。该反应可进入阿扑嘌呤的五环构架,并能构建其他抗布雷德和笼状复杂分子。
