Abstract:
Functionalized tryptamines are targets of interest for development as small molecule therapeutics. The ring opening of aziridines with indoles is a powerful method for tryptamine synthesis where isomer formation can be controlled. 3,5-Dinitrobenzoyl (DNB)-protected aziridines undergo regioselective, enantiospecific ring opening to produce β-substituted tryptamines for a series of indoles. Attack at the more substituted aziridine carbon occurs in an SN2-like fashion to generate DNB-tryptamine products as synthetic precursors.

Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
