Diindolylmethanes, IV: Acid Catalyzed Condensation of 3-Methylindole and Methyl Tryptophanate with Sterically Hindered Aromatic Aldehydes
Pindur, Ulf
, p. 790 - 794 (1980)
The 3-substituted indoles 1 and 2 react with 2,6-dimethoxybenzaldehyde (3a) to yield the diindolylmethanes 4 and 6 by acid catalysis.The reaction of 2 with 3a also yields the tetrahydro-β-carboline 7.The sterically hindered mesitylaldehyde (3b) reacts only with the indole 1 to give the 2,2'-diindolylmethane 5, while the tryptophane methyl ester 2 yields the tetrahydro-β-carboline 8 only.
