Synthesis of Methylcubane and Cyclopropylcubane. The Cubane-1,4-diyl Route
摘要:
Details for preparation of 1,4-diiodocubane from cubane-1,4-dicarboxylic acid are given. The diiodide is used to generate cubane-1,4-diyl, a nonisolable intermediate. Additions to the diyl are shown to provide for the ready synthesis in good yield of methylcubane, 1,4-dimethylcubane, cyclopropylcubane, etc.

time-dependent, irreversible inactivators of monoamine oxidase B (MAO B). Substrate protects the enzyme from inactivation, but beta-mercaptoethanol does not, suggesting that these compounds are mechanism-based inactivators. All three compounds were also substrates for MAO B with partition ratios ranging from 152 to 536. The 4-substituted analogues were more potentinactivators than the unsubstituted analogue
