Liu, Kevin G.,Robichaud, Albert J.
, p. 461 - 463 (2007)
A novel and efficient two-step synthetic sequence for the preparation of 3,3-disubstituted oxindoles was developed starting from arylhydrazines and α-branched aldehydes via Fischer indole type synthesis followed by imine oxidation.

An efficient copper-catalyzed intramolecular N-arylation was performed by using substituted 2-(2-bromoaryl)acetamide with a small amount of Cu 2O and benzene-1,2-diamine as catalytic system under aerobic conditions, which provided good to excellent yields of oxindoles with tolerance of a wide variety of substrates.
Conformationally constrained ortho- Anilino diaryl ureas: Discovery of 1-(2-(1′-Neopentylspiro[indoline-3,4′-piperidine]-1-yl)phenyl) -3-(4-(trifluoromethoxy)phenyl)urea, a potent, selective, and bioavailable P2Y1 antagonist

Preclinical antithrombotic efficacy and bleeding models have demonstrated that P2Y1 antagonists are efficacious as antiplatelet agents and may offer a safety advantage over P2Y12 antagonists in terms of reduced bleeding liabilities. In this article, we describe the structural modification of the tert-butyl phenoxy portion of lead compound 1 and the subsequent discovery of a novel series of conformationally constrained ortho-anilino diaryl ureas. In particular, spiropiperidine indoline-substituted diaryl ureas are described as potent, orally bioavailable small-molecule P2Y1 antagonists with improved activity in functional assays and improved oral bioavailability in rats. Homology modeling and rat PK/PD studies on benchmark compound 3l will also be presented. Compound 3l was our first P2Y1 antagonist to demonstrate a robust oral antithrombotic effect with mild bleeding liability in the rat thrombosis and hemostasis models.
Copper-catalyzed domino coupling reaction: An efficient method to synthesize oxindoles

An efficient and novel procedure for a copper catalyzed domino coupling reaction has been developed, which afforded various oxindoles in good to excellent yields with tolerance of various substituents. In addition, this method could be applied to synthesize horsfiline and coerulescine in few steps with high total yields. The Royal Society of Chemistry 2012.

The present invention provides novel ureas containing N-aryl or N-heteroaryl substituted heterocycles and analogues thereof, which are selective inhibitors of the human P2Y1 receptor. The invention also provides for various pharmaceutical compositions of the same and methods for treating diseases responsive to modulation of P2Y1 receptor activity.
New spirocyclic oxindole synthesis based on a hetero claisen rearrangement
Mao, Zhan,Baldwin, Steven W.
, p. 2425 - 2428 (2007/10/03)
(Equation Presented) A new method for preparing spirocyclic oxindoles is presented. Featuring a [3,3]-sigmatropic enolate rearrangement, the three-step process converts carboxylic acid starting materials to oxidnole products in overall yields of 52-76%. The enolate rearrangement step occurs at -78 °C and provides easy access to oxindole products that have previously been difficult to prepare.
