Total syntheses of trisphaeridine (3)
and norchelerythrine (4), fully
aromatized phenanthridine and benzo[c]phenanthridine alkaloids, were
accomplished via the internal arylâaryl coupling reaction of
halo amides protected by a methoxymethyl group with the palladium reagent,
followed by reduction with lithium aluminium hydride and treatment with hydrochloric
acid.
完成了trisphaeridine(3)和norchelerythrine(4)的全合成,这是两个完全芳香化的菲啶和苯并[c]菲啶生物碱,通过带有甲氧基甲基保护的卤代酰胺与钯试剂的内部芳基-芳基偶联反应实现,随后用氢化铝锂还原并使用盐酸处理。
