金沢大学大学院自然科学研究科生理活性物質科学金沢大学薬学部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\u27-bispyrrolo[2,3-b]indole compound, whose structure was unequivocally determined by X-Ray crystallographic analysi
