We have proven that the biomimetic-like synthesis of cannabinoidsfrom citral and the corresponding phenolic counterpart may well be carried out using water as a solvent. The influence of different additives such as surfactants was also analyzed. Rationalization of the reaction mode and regiochemistry of the processes were provided in terms of “on water” and “in water” reactions. The same reactions
coupled, in an aromatization-driven single operational step, the condensation of citral and alkylresorciniols to homoprenylchromenes and their in situ deconstructive annulation to benzo[c]chromenes. This process was applied to a total synthesis of cannabinol (CBN, 5) and to its molecular editing.
大麻素(CBC,3)的热降解主要受阳离子反应的影响,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工艺的发展,该工艺在芳构化驱动的单个操作步骤中将柠檬醛和烷基间苯二酚缩合为高异戊二烯基色烯,并将它们原位解构性环化为苯并[ c ]色烯。此过程应用于大麻酚(CBN,5)的全合成及其分子编辑。
