Abstract

A revised modular approach to various synthetic (–)-trans-Δ 8 -THC derivatives through late-stage Suzuki–Miyaura cross-coupling reactions is disclosed. Ten derivatives were synthesized allowing both sp 2 - and sp 3 -hybridized cross-coupling partners with minimal β-hydride elimination. Importantly, we demonstrate that a para-bromo-substituted THC scaffold for Suzuki–Miyaura cross-coupling reactions has been initially reported incorrectly in recent literature.
