Indole-3-carbaldehyde (I3A), also known as indole-3-aldehyde and 3-formylindole, is a metabolite of dietary L-tryptophan which is synthesized by human gastrointestinal bacteria, particularly species of the Lactobacillus genus.
At very low concentrations, however, it has a flowery smell, [3] and is a constituent of many perfumes. It also occurs in coal tar. It has been identified in cannabis. [4] It is the main volatile compound in stinky tofu. [5] When indole is a substituent on a larger molecule, it is called an indolyl group by systematic nomenclature.
[3] Ferrocenecarboxaldehyde, owing to the versatility of the formyl group, is a precursor to many ferrocene-modified compounds. With a Wittig reagent, it converts to vinylferrocene and related derivatives. [5] With primary amines, ferrocenecarboxaldehyde condenses to give imines. The azomethine derivative undergoes 1,3-cycloaddition to C 60. [6]
