Convenient modification of the Leimgruber-Batcho indole synthesis: reduction of 2-nitro-β-pyrrolidinostyrenes by the FeCl3–activated carbon–N2H4∙H2O system
摘要:
A new catalytic system containing ferric chloride, activated carbon, and hydrazine has been proposed for the reductive cyclization of beta-dialkylamino-2-nitrostyrenes to give the corresponding indoles (Leimgruber-Batcho synthesis). Various substituted indoles may be obtained in high yield under these conditions.

Twelve new N, N-dialkylated-5, 6-methylenedioxytryptamines and N-cyclopropyl-5, 6-methylenedioxytrypt-amine were prepared as hybrids of known psychoactive phenylethylamines and tryptamines. Novel, more convenient syntheses of N-methyl- and N-benzylcyclopropylamine are described.

Reductive heterocyclization reactions of various 1-nitro-2-(2-nitroaryl)ethenes to indoles were investigated. In the presence of indium/AcOH in toluene or benzene, 1-nitro-2-(2-nitroaryl)ethenes were cyclized to give corresponding indoles in good yields.
