  Synthesis of Demethoxy-Lycoraminone

  摘要：

  Demethoxy-lycoraminone (8) was prepared in several steps starting from the appropriate benzo[c]azepine dione derivative (9). Ketone (9) was protected as a ketal group followed by methylation on the azepine nitrogen atom. After reduction of the imide carbonyl groups, deprotection, demethylation and ring closure were carried out as a one-pot reaction in methanesulfonic acid in the presence of racemic methionine.
