Using a combination of Au nanoparticle-catalyzed oxidation under an O2 atmosphere and a Ti-doped montmorillonite (Ti-MMT)-catalyzed tandem arylation/double cyclization, we developed an original and highly selective method for the synthesis of ortho-tetrahydrocannabinol derivatives from simple substrates. The reaction sequence could be performed in two steps in batch mode or in a single operation in continuous-flow reactors. The abnormal regioselectivity was proposed to be the result of the non-innocent role of the MMT support, TiIV cation coordination, and a Lewis acid-assisted Br?nsted acid (LBA) mechanism.
