Libocedrol

An early example " was the surprisingly selective oxidation of methoxythymol (212) with alkaline ferricyanide to libocedrol (213 49%) further cross-coupling of the latter with more monomer using the same reagent yielded (46%) the trimeric libocedroxythymoquinone (214 46%). Lophocerine (215) also formed a dimer, isopilocereine (216 32%), on exposure to ferricyanide, together with traces of the...
