1—Azatriene cyclisation as a route to annelated pyrido[4,3- b ]indoles
摘要:
Derivatives of indole-3-carbaldehyde oxime have been prepared that bear a carbon-carbon double bond at C-2 and a five- or six-membered ring linking the alpha-carbon artom of the vinyl group and the indole nitrogen atom. Compound 9, with a five-membered ring linking the two atoms, failed to undergo a cyclisation reaction on heating. However the oximes 16 and 22, with a six-memberd ring linking the two atoms. cyclised in boiling toluene. The cyclisation led to the formation of the pyrido-indoles 17 and 18, respectively.
