Intramolecular Vinylation of Aryl Rings by Vinyl Cations
Fang, Jian,Brewer, Matthias
, p. 7384 - 7387 (2018)
A Lewis acid mediated intramolecular electrophilic vinylation of aryl rings by vinyl cations is reported. This reaction takes advantage of β-hydroxy-α-diazo ketones as vinyl cation precursors and provides good yields of tricyclic 1-indenones that contain
Trimethylchlorosilane-Mediated Mild α-Chlorination of 1,3-Dicarbonyl Compounds Promoted by Phenyliodonium Diacetate

Trimethylchlorosilane was used as chlorine source for the α-chlorination of 1,3-dicarbonyl compounds with phenyliodonium diacetate as oxidant at room temperature. The reaction allows the selective synthesis of α-monochlorinated products from different kinds of 1,3-dicarbonyl compounds in good yield. The potential possibility of this conversion for bromination has also been investigated.

We have designed a series of potent EP1 receptor antagonists. These antagonists are a series of 2-(1H-indazol-1-yl)-thiazoles in which the core structure was replaced with pyrazole-phenyl groups. In preliminary conscious rat cystometry experiments, two representative candidates, 2 and 22, increased bladder capacity. In particular, the increase using 22 was approximately 2-fold that of the baseline. More detailed profiling of this compound and further optimization of this series promises to provide a novel class of drug for treating overactive bladder (OAB).
Iridium-catalyzed reaction of enones with alcohols affording 1,3-diketones
Obora, Yasushi,Nakamura, Kazuhiro,Hatanaka, Shintaro
supporting information; experimental part, p. 6720 - 6722 (2012/07/17)
An iridium-catalyzed coupling reaction of alcohols with enones has been successfully developed providing access to 1,3-diketones with high selectivity in good yields. This reaction provides an atom-economical route to 1,3-diketones from readily available
BICYCLIC NITROGEN-CONTAINING HETEROCYCLIC COMPOUNDS

Page/Page column 41, (2010/03/02)
A nitrogen-containing bicyclic heterocyclic compound represented by the following formula (1) is provided. When the compound or a salt thereof is administered to a human being or an animal, the compound has a strong antagonistic action against EP1 recepto
1,3-Diarylcycloalkanopyrazoles and diphenyl hydrazides as selective inhibitors of cyclooxygenase-2
Sui, Zhihua,Guan, Jihua,Ferro, Michael P.,McCoy, Kathy,Wachter, Michael P.,Murray, William V.,Singer, Monica,Steber, Michele,Ritchie, Dave M.,Argentieri, Dennis C.
, p. 601 - 604 (2007/10/03)
Novel 1,3-diarylcycloalkanopyrazoles 1, and diphenyl hydrazides 2 were identified as selective inhibitors of cyclooxygenase-2. The 1,3-diaryl substitution pattern of the pyrazole ring in 1 differentiates these compounds from most of the known selective COX-2 inhibitors that contain two aryl rings at the adjacent positions on a heterocyclic or a phenyl ring. Similarly, the two phenyl rings in 2 are also separated by three atoms. SAR of both phenyl rings in 1 and 2, and the aliphatic ring in 1 will be discussed. (C) 2000 Elsevier Science Ltd.

InCl3: A new Lewis acid catalyst for reactions with α-diazocarbonyl compounds
Sengupta, Saumitra,Mondal, Somnath
, p. 8685 - 8688 (2007/10/03)
The use of InCl3 as a Lewis acid catalyst in diazocarbonyl S-H insertion reactions, nitrile cyclizations and addition reactions to aldehydes and ketones is described.
