Studies toward the synthesis of menogaril: Synthesis of a-ring precursors and their conversion to the tetracyclic core via the benzannulation reaction

A model study for the synthesis of menogaril is reported which involves the benzannulation reaction of a Fischer carbene complex with an alkyne that contains the A-ring of the tetracyclic core of menogaril. The synthesis of methoxy and benzyloxy derivatives of this alkyne are reported as well as the reaction of the methoxy derivative with an o-methoxyphenyl carbene complex to generate a tricyclic naphthol containing three of the four rings of menogaril core. Completion of the model study and the synthesis of the tetracyclic anthracyclinone core of menogaril was accomplished by an intramolecular Friedel-Crafts cyclization.
Reaction of Azoalkanes with Isolable Cation Radical Salts

Three tertiary azoalkanes related in the sense acyclic, cyclic, and bicyclic are shown to evolve nitrogen upon oxidation with stable cation radical salts.Thus azo-tert-octane (ATO), 3,3,6,6-tetramethyl-1,2-diazacyclohexene (TMDAC), and 1,4-dimethyl-2,3-diazabicyclooct-2-ene (Me2DBO) react rapidly with thianthrenium perchlorate (Th(.1+)ClO4(1-)), tris(p-bromophenyl)aminium hexachloroantimonate (TBPA(.1+)SbCl6(1-)), and TBPA(.1+)SbF6(1-).The ether and olefin products, which are formed in high yield in CH2Cl2/MeOH solvent, are not those expected from the usual free-radical decomposition of azoalkanes but instead implicate carbocations.Althrough the reaction stoichiometry clearly requires 2 equiv of cation radical salt to one of azoalkane, the mechanism is not yet clearly defined.A complication in these studies is found in the ability of certain cation radical salts to oxidize more azoalkane than expected based on the 2:1 stoichiometry.
