  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.

• An unexpected rearrangement of the benzofurobenzazepine skeleton of galanthamine-type alkaloids

  Attempted cyclisation of N-methylated Spiro benzazepine-cyclohexenone (5) into the corresponding N-methyl tetracyclic unit of galanthamine-type alkaloids (6) instead gave an unexpected rearrangement to yield a cyclopentanoisoquinolinone derivative (7). Methylation of the tetrahydrobenzofurobenzazepine tetracycle resulted in the expected N-methyl derivative 6, and the anomalous product 8, with structure similar to that of 7. (C) 2010 Elsevier Ltd.
