摘要

抄録: A unique synthetic method for melatonin was established through biologically promising synthetic intermediates. 1-Hydroxymelatonin was prepared as crystals for the first time. It reacted with 85% formic acid to give (±)-3a, 3a'-bispyrrolo [2, 3-b] indole compound, whose structure was unequivocally determined by X-Ray crystallographic analysis
