摘要

The dehydrogenation step proceeded satisfactorily only with sulfur fusion; palladium catalysts in our hands resulted in erratic and scale-dependent yields, and also formed the hydrogenolysis product of 3 as a byproduct that was difficult to remove. Subsequent functionalization of the dehydrogenation product followed routine paths. Demethylation with trimethylsilyl iodide gave 4; acetylation followed by bromination (NBS), and treatment with
