Brønsted Acid-Promoted Cascade Alkylation/Cyclization of Pyrroles with N,N-Dimethylaminomethyleneglutaconic Acid Dinitrile: A Concise Route to Cyclopenta[b]pyrroles

Kaikai Wu, +5 more
- 12 Oct 2015 - 
TL;DR: In this paper, the 2-alkylated pyrrole was confirmed by isolation and transformation of the reactio ni nter-mediate, i.e., the 2 -alkylation pyrrorole.
Journal ArticleDOI

Substitution of Alcohols by N-Nucleophiles via Transition Metal-Catalyzed Dehydrogenation

Qin Yang, +2 more
- 18 Jun 2015 - 
TL;DR: In this article, transition metal-catalyzed dehydrogenative substitution of alcohols by N-nucleophiles has been studied for the first time in the last decade.
Journal ArticleDOI

α,β-Unsaturated N-Acylindoles: An Alternative Class of Michael Acceptors and Their Application in Asymmetric Borylation.

Quanbin Jiang, +8 more
- 25 May 2018 - 
TL;DR: The present work provides an alternative class of Michael acceptors, that is, α,β-unsaturated N-acylindoles, for potential asymmetric transformations, and affording the enantioenriched products in excellent yields with up to 99% ee.
Journal ArticleDOI

Highly Efficient Route to Diselenides from the Reactions of Imines and Selenium in the Presence of Carbon Monoxide and Water

Xiaodan Zhao, +7 more
- 01 May 2005 - 
TL;DR: In this paper, the reaction of selenium with imines (RR 1 C¼NR 2 ) of aldehydes and ketones in the pres- ence of carbon monoxide, water and triethylamine lead to reductive selenation, on aerobic work-up, to afford symmetrical diselenides in good to excellent yields.
Journal ArticleDOI

Reductive desulfurization of organosulfur compounds with sodium in liquid ammonia

Zhengkun Yu, +1 more
- 01 Jan 1998 - 
TL;DR: In this article, it was shown that 95% sulfur removal rate was achieved when dialkyl mono or polysulfides were treated with Na in liquid ammonia, while phenylthio derivatives gave thiophenol as the major product and dithiophenols as minor products.
