A Revised Modular Approach to (-)-trans-Δ8-THC and Derivatives Through Late-Stage Suzuki-Miyaura Cross-Coupling Reactions.

A revised modular approach to various synthetic (-)-trans-Δ8-THC derivatives through late-stage Suzuki-Miyaura cross-coupling reactions is disclosed. Ten derivatives were synthesized allowing both sp2- and sp3-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.
