[Definition]

ChEBI:Indole-4-carbaldehyde is a heteroarenecarbaldehyde that is indole in which the hydrogen at position 4 has been replaced by a formyl group. It has a role as an algal metabolite. It is a member of indoles and a heteroarenecarbaldehyde.

[General Description]

Indole-4-carboxaldehyde participates in the synthesis of arcyriacyanin A. Synthesis of 4-indole-4-carboxaldehyde has been reported. Intramolecular Friedel-Crafts (FC) acylation of indole-4-carboxaldehyde has been reported.
[Synthesis]

Tetrapropylammonium perruthenate (0.3 g, 0.85 mmol) was added in portions to a mixture of alcohol product from 1H-Indole-4-Methanol (2.5 g, 17 mmol), N-methylmorpholine N-oxide (3.0 g, 25 mmol) and 4 A molecular sieves (3.0 g) in anhydrous methylene chloride (30 mL) at room temperature. The mixture was stirred at room temperature under nitrogen for 1 h and then filtered. The filtrate was concentrated in vacuo, and the residue was purified by chromatography (SiO2, CH2Cl2) to provide Indole-4-carboxaldehyde as a white powder (2.0 g, 80percent): 1H NMR (300 MHz, CDCl3) δ10.2 (s, 1H), 8.52 (br s, 1H), 7.64-7.69 (m, 2H), 7.31-7.44 (m, 3H), CI MS m/z=146 [C9H7NO+H]+.
