Reactions of 2-aminoimidazoles with aldehydes. Hydroxyalkylation and cycloaddition.
摘要:
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.
