概要:

金沢大学大学院自然科学研究科生理活性物質科学<br />金沢大学薬学部<br />Indigo was converted to 2,2′-bisindole by the direct reduction with zinc in acetic acid and acetic anhydride under argon or hydrogen atmosphere. Reduction with tin and iron afforded … 3-acetoxy-2,2′-bisindole predominantly. Useful building blocks such as 1-acetyl-2,3-dihydro-, 3-acetoxy-3′-acetyl-, and 3-acetoxy-1,3′-diacetyl-2,2′-bisindoles were also produced depending on metal and reaction conditions. 続きを見る
