A process for the preparation of substantially pure diverse known and novel cannabinoids 1 and 2, which include Δ9-tetrahydrocannabinol (7), tetrahydrocannabivarin (9), cannabidiol (11), cannabidivarin (12) and other naturally occurring tetracyclic and tricyclic cannabinoids and other synthetic tetracyclic and tricyclic analogues, via intermediates 3, 6, 4 and 5, using a cascade sequence of allylic rearrangement, aromatization and, for the tetracyclic cannabinoids, further highly stereoselective and regioselective cyclization. These synthesized cannabinoids can more easily be obtained at high purity levels than cannabinoids isolated or synthesized via known methods. The cannabinoids 2, including Δ9-tetrahydrocannabinol (7), tetrahydrocannabivarin (9), are obtained containing very low levels of isomeric cannabinoids such as the undesirable Δ8- tetrahydrocannabinol. The known and novel analogues with variation in aromatic ring substituents, whilst easily synthesized with the new methodology, would be much more difficult to make from any of the components of cannabis or cannabis oil.
一种制备基本纯净的多种已知和新型大麻素1和2的方法,其中包括Δ9-四氢大麻酚(7)、四氢大麻烯酚(9)、大麻二酚(11)、大麻二烯酚(12)以及其他天然存在的四环和三环大麻素及其他合成的四环和三环类似物,通过中间体3、6、4和5,使用烯基重排、芳香化和对于四环大麻素而言,进一步高度立体选择性和区域选择性的环化级联序列。这些合成的大麻素可以比通过已知方法分离或合成的大麻素更容易地以高纯度水平获得。其中包括Δ9-四氢大麻酚(7)、四氢大麻烯酚(9)的大麻素2,含有非常低水平的异构大麻素,例如令人不满的Δ8-四氢大麻酚。具有芳香环取代基变化的已知和新型类似物,虽然可以通过新方法轻松合成,但要从大麻或大麻油的任何成分中制备则更加困难。
