The reaction between 2-aminoimidazoles and aldehydes affords mono- and disubstituted hydroxyalkylaminoimidazoles and tetrahydropurine derivatives. The formation of the tetrahydropurine is believed to proceed via an intermolecular hetero [2+4] cycloaddition between 2-aminoimidazole and its corresponding Schiff base.

A one-step synthesis of the nitrogenous marine pigment parazoanthoxanthin A (1a) and related pseudozoanthoxanthin A (2a) from 2-aminoimidazole is described. The key step involves hydroxyalkylation of the C3N3 heterocycle with acetaldehydes and pyruvic acid.
