A process for the synthesis of Cannabidiol of formula (1):
is herein disclosed. The process comprises contacting a solution [solution (S1)] of (+)-p-mentha-diene-3-ol of formula (4)
or an ester thereof and olivetol of formula (3):
with a solution [solution (S2)] of a non-supported Lewis acid in a continuous flow reactor and treatment of the resulting mixture with a basic solution.
The process offers the advantage that it can be conveniently carried out on an industrial scale while avoiding the formation of abnormal CBD and THC (Δ9-tetrahydrocannabinol).
