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

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

概要: Irradiation (≥300 nm) of methyl 2-phenyl-3, 1-benzoxazepine-5-carboxylate in an alcohol afforded the Z-isomer of methyl 3-alkoxy-2-(2-benzamidophenyl)-acrylate as the major addition product. In contrast, thermal reaction of the oxazepine with a primary alcohol in the presence of triethylamine led to the exclusive formation of the corresponding E-isomer. The same kinds of Michael addition products were also obtained stereoselectively from 3, 1-benzoxazepines having an acetyl group at the 5-position under these conditions. The interrelation between the stereoisomers obtained from the oxazepine and an alcohol under these two conditions was established by photochemical equilibration, and the stereochemistry of the two isomers was determined by proton magnetic resonance spectroscopy. An explanation is proposed for the observed stereoselectivities in the two kinds (photochemical and thermal) of reactions. 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 />According to the definition of the ideal synthetic method, an example aimed at the leads for an α2 blocker, an inhibitor of platelet aggregation, and an anti-osteoporosis agent is established starting from tryptamine. The originality rate, the intellectual property, and the application potential factors of the method are 71, 54, and 100, respectively. The method employs only conventional reagents and reaction conditions without using any protecting groups.{A figure is presented}. © 2006 The Japan Institute of Heterocyclic Chemistry 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 />For evaluating the effectiveness of organic synthesis, both intellectual property factor (IP F) and application potential factor (APF) are proposed. As a representative example, a highly effective synthetic method with IPF value of 53.8 and APF value of 100 has been established starting from indigo directing toward an antibiotic, 6-cyano-5-methoxy-12-methylindolo[2,3-a]carbazole, using only conventional reagents without using any protecting groups. © 2004 The Japan Institute of Heterocyclic Chemistry All rights reserved. 続きを見る

概要: Cyclopentane ring annelation methods for 2-pyridone derivatives are provided by cyclobutane ring expansion of 1, 2-dihydrocyclobuta [c] pyridin-3 (4H)-ones having an appropriate function at the l-position. Since the latter compounds are readily accessible from 4-alkoxy-2-pyridones via our two-step procedure (Kaneko-Naito method), the methods seem to have wide applicability for the synthesis of cyclopenta [c] pyridines. 続きを見る

概要: 金沢大学医薬保健研究域薬学系<br />金沢大学名誉教授<br />X-Ray analyses of 1-hydroxyyohimbine derivatives clearly show the deviation of the N(1 )-O bond from the indole molecular plane. This phenomenon supports our working hypothesis "bishomoallylic conjugation". The deviation is responsible for the unprecedented nucleophilic substitution reaction in 1-hydroxyindole chemistry and effected the synthesis of novel 7β-heteroarylyohimbine and 4aα-heteroaryl-1,2,3,4-tetrahydro-β-carboline derivatives from the corresponding 1-hydroxyindole derivatives. © 2008 The Japan Institute of Heterocyclic Chemistry All rights reserved. 続きを見る
