Journal ArticleDOI
Ultra-remote stereocontrol by conformational communication of information along a carbon chain
TL;DR: St stereocontrol is demonstrated over a reaction taking place more than 20 bond lengths from the controlling centre, corresponding to a linear distance of over 2.5 nm, providing a chemical model of allostery and might serve as a molecular mechanism for communicating and processing information.
Journal ArticleDOI
Intramolecular Pd-Mediated Processes of Amino-Tethered Aryl Halides and Ketones: Insight into the Ketone α-Arylation and Carbonyl-Addition Dichotomy. A New Class of Four-Membered Azapalladacycles
TL;DR: The dichotomy between ketone alpha-arylation and carbonyl-addition in the reactions of omega-(2-haloanilino) alkanones has been rationalized by the intermediacy of unprecedented four-membered azapalladacycles, from which X-ray data and chemical behavior are reported.
Journal ArticleDOI
Synthesis and Reactivity of Four-Membered Azapalladacycles Derived from N,N-Dialkyl-2-iodoanilines: Insertion Reactions of Carbenes into the Carbon-Palladium Bond
TL;DR: In this article, three four-membered azapalladacycles derived from N,N-dialkyl-2-iodoanilines have been synthesized: Pd(κ2-C6H4NMe2-2)I(PPh3)
Journal ArticleDOI
Slow interconversion of enantiomeric conformers or atropisomers of anilide and urea derivatives of 2-substituted anilines
Thomas Adler,Josep Bonjoch,Jonathan Clayden,Mercè Font-Bardia,Mark Pickworth,Xavier Solans,Daniel Solé,Lluís Vallverdú,Lluís Vallverdú +8 more
TL;DR: For the first time, the rates of Ar-N rotation in 2-substituted N,N'-diarylureas have been established and mainly fall in the region of 50-70 kJ mol(-1) with a relatively weak dependence on substituent size.
Journal ArticleDOI
Palladium-catalysed intramolecular annulation of 2-haloanilines and ketones: enolate arylation vs. nucleophilic addition to the carbonyl group.
TL;DR: Two alternative annulation pathways involving either the enolate arylation or the addition to the ketone carbonyl group can operate in the Pd-catalysed intramolecular coupling of 2-haloanilines and ketones.
