Houghton, Roy P.,Voyle, Martyn,Price, Raymond
, p. 183 - 188 (1983)
When treated with potassium t-butoxide in dimethyl sulphoxide the chromium tricarbonyl complex of 3-(2-fluorophenyl)propan-1-ol underwent a rapid intramolecular nucleophilic substitution to give the corresponding complex of chroman, from which the heteroc

One-Pot, Tandem Wittig Hydrogenation: Formal C(sp3)-C(sp3) Bond Formation with Extensive Scope

A one-pot, tandem Wittig hydrogenation of aldehydes with stabilized ylides is reported, representing a formal C(sp3)-C(sp3) bond construction. The tandem reaction operates under mild conditions, is high yielding, and is broad in scope. Chemoselectivity for olefin reduction is observed, and the methodology is demonstrated in the synthesis of lapatinib analogues and a formal synthesis of (±)-cuspareine. Early insights suggest that the chemoselectivity observed in the reduction step is due to partial poisoning of the catalyst, after step one, thus adding to the power of the one-pot procedure.

The development of a new series of p38α inhibitors resulted in the identification of two clinical candidates, one of which was advanced into a phase 2 clinical study for rheumatoid arthritis. The original lead, an lck inhibitor that also potently inhibited p38α, was a screening hit from our kinase inhibitor library. This manuscript describes the optimization of the lead to p38-selective examples with good pharmacokinetic properties.

3-arylpropanoate esters through the palladium-catalyzed reaction of aryl halides with acrolein diethyl acetal
Battistuzzi, Gianfranco,Cacchi, Sandro,Fabrizi, Giancarlo,Bernini, Roberta
, p. 1133 - 1136 (2007/10/03)
The reaction of aryl halides with acrolein diethyl acetal in the presence of Pd(OAc)2, n-Bu3N, and n-Bu4NCl in DMF at 90°C affords ethyl 3-arylpropanoates. A variety of functional groups are tolerated in the aryl halides, including ether, aldehyde, ketone, ester, nitrile, and nitro groups. ortho-Substituents do not hamper the reaction. 3-Arylpropanoate esters were isolated in good to excellent yields with many neutral, electron-rich and electron-poor aryl iodides and electron-poor aryl bromide. Neutral and electron-rich aryl bromides gave the desired ester in moderate yields.
