The thermal degradation of cannabichromene (CBC, ) is dominated by cationic reactions and not by the pericyclic rearrangements observed in model compounds. The rationalization of these differences inspired the development of a process that coupled, in an aromatization-driven single operational step, the condensation of citral and alkylresorciniols to homoprenylchromenes and their deconstructive annulation to benzo[]chromenes. This process was applied to a total synthesis of cannabinol (CBN, ) and to its molecular editing.
大麻色烯(CBC)的热降解主要由阳离子反应主导,而不是模型化合物中观察到的周环重排。这些差异的合理化激发了一种过程的发展,该过程在一个芳香化驱动的单一操作步骤中,将柠檬醛和烷基间苯二酚缩合为同丙烯基色烯,并将其解构性环合为苯并[]色烯。该过程被应用于大麻醇(CBN)的全合成及其分子编辑。
