Studies on the syntheses of heterocyclic compounds. Part CDXXXIV. A novel total synthesis of olivacine (1,5-dimethyl-6H-pyrido[4,3-b]-carbazole)
Abstract
The tumour-inhibiting alkaloid olivacine (1) has been synthesised in one step by heating indole and 4-(1-hydroxyethyl)-3-methoxymethyl-2-methylpyridine (14) in 47% hydrobromic acid.
