Sodium borohydride reduction of 1-(2′-Bromobenzoyl)-2-methyl-3,4-dihydro-6,7-methylenedioxyisoquinolinium iodide () gave a mixture of alcohols which on irradiation in dil.HCl afforded (±) oliveroline and (±)ushinsunine.

Moderate XPhos precatalyst loading (10 mol %) and short reaction times (30 min) were sufficient to mediate the arylations. Alkaloids 1–5 were successfully prepared, while (−)-artabonatine A was revised to syn-isomer 30. Consequently, (−)-artabonatine E likely also has a syn-configuration (31).
