概要: 1-Hydroxy-2,3-dimethylindole (1) has been prepared for the first time. Under atmospheric oxygen, 1 was converted rapidly into 3-hydroxy-2,3-dimethyl- 3H-indole N-oxide (2). The structure was deduced, based on its products obtained … by the reaction with Ac2O in pyridine and confirmed by X-ray single crystallographic analysis. 続きを見る

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 ace … tic 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

概要: Photoirradiation of 1-ethoxy-2-phenylindole in methanol and the reaction of 1-hydroxy-2-phenylindole with tosyl chloride … produced 6-ethoxy- and 6-tosyloxy-2-phenylindoles, respectively, as minor products. The latter was derived to 6-ethoxy-2-phenylindole. The structure is determined by direct comparison of the spectral data with those of the authentic 4-, 5-, 6-, and 7-ethoxy-2-phenylindoles whose syntheses are reported in detail. © 2012 The Japan Institute of Heterocyclic Chemistry. 続きを見る
