The present invention relates to a process for the preparation of diverse known and novel cannabinoids 5, which include cannabigerol (CBG, 1), cannabigerolic acid (CBGA, 2), cannabigerovarin (CBGV, 3), cannabigerovarinic acid (CBGVA, 4) and other naturally occurring monocyclic cannabinoids and other analogues from simple inexpensive starting materials using a cascade sequence of allylic rearrangement and aromatization. Novel cannabinoids of series 5 are also claimed as part of the invention. These synthesized cannabinoids, unlike the minor cannabinoids isolated from Cannabis saliva or synthesized from the condensation reactions such as the reactions of substituted resorcinols with monoterpenes, are much easier to obtain at high purity levels. In particular, these cannabinoids, including but not limited to cannabigerol (CBG, 1), cannabigerolic acid (CBGA, 2), cannabigerovarin (CBGV, 3) and cannabigerovarinic acid (CBGVA, 4) are obtained without contamination with impurities with variation in RA and RB (e.g. contamination of CBG with CBGV).
本发明涉及一种制备多种已知和新型大麻素的过程,包括大麻酚醇(CBG, 1)、大麻酚醇酸(CBGA, 2)、大麻酚酮(CBGV, 3)、大麻酚酮酸(CBGVA, 4)等以及其他天然存在的单环大麻素和其他类似物,利用一系列烯丙基重排和芳构化的级联序列从简单廉价的起始原料中制备。系列5的新型大麻素也作为本发明的一部分声明。与从大麻唾液中分离或通过与单萜烃的缩合反应等反应合成的微量大麻素不同,这些合成的大麻素更容易以高纯度水平获得。特别是这些大麻素,包括但不限于大麻酚醇(CBG, 1)、大麻酚醇酸(CBGA, 2)、大麻酚酮(CBGV, 3)和大麻酚酮酸(CBGVA, 4),可以在不受杂质污染的情况下获得,RA和RB的变化(例如CBG与CBGV的污染)。
