An asymmetric Brønsted acid catalyzed and biomimetic cyclization of 1-aryl terpenols as a platform strategy for the synthesis of Δ9-cis-tetrahydrocannabinoids is described. This synthesis features the most direct synthetic access to this product class and requires only 3 steps from readily available precursors with exceptionally low catalyst loadings of as low as 0.5 mol % (MOM=methoxymethyl, IDPi
Various aspects of this disclosure relate to methods to lower the activation energy of the cannabinoid decarboxylation reaction by performing the decarboxylation reaction in the gas phase.
