  A common and general access to berberine and benzo [c] phenanthridine alkaloids

  摘要：

  The S(RN)1 reactions between o-iodobenzamides and the enolate anion from 2-acetyl homoveratric acid lead to key tricyclic compounds which are easily converted to either berberine or benzo [c] phenanthridine ring systems providing thus a high-yielding and versatile access to both classes of alkaloids.

  Flavanone and chromanone were also found to be facile substrates with the developed catalytic system. Mechanistic studies revealed the active catalytic species and the role of water in the reaction process as hydroxy and proton sources. Employing the developed method, total synthesis of cytosporone A was achieved in two steps and that of cytosporones B–C was achieved in three steps starting from resorcinol
