Facile and rapid immobilization of copper(II) bis(oxazoline) catalysts on silica: application to Diels-Alder reactions, recycling, and unexpected effects on enantioselectivity
Patrick O'Leary,Nico P. Krosveld,Krijn P. de Jong,Gerard van Koten,Robertus J. M. Klein Gebbink +4 more
TL;DR: In this paper, two chiral copper(II) bis(oxazoline) complexes have been immobilized on silica via electrostatic interactions using a remarkably straightforward procedure, and they were tested in a standard Diels-Alder reaction and gave surprising results.

Dynamic equilibria in the products of intramolecular Buchner additions of diazoketones to aryl rings bearing methoxy substituents.
TL;DR: The aromatic addition products in this study display more complex dynamic equilibria due to conjugation with the methoxy group; the experimental evidence for this is discussed in detail.

Stereocontrol in the intramolecular Buchner reaction of diazoketones
TL;DR: Rhodium(II) acetate catalysed intramolecular Buchner cyclisation of a series of diazoketones 1 proceeds with excellent diastereoselectivity to produce the trans substituted azulenones 2, which exist as a rapidly equilibrating cycloheptatriene–norcaradiene system, from which the norcaradienes tautomers can be efficiently trapped as PTAD cycloadducts 4.

Hydroxyamide-Based Ligands and Their Use in the Asymmetric Catalysis of Key Organic Transformations
Paul Geoghegan,Patrick O'Leary +1 more
TL;DR: Asymmetric ligands whose key functional component consists of an amide and hydroxyl functional groups, in the absence of other co-ordinating groups, are a relatively recent development in asymmetric catalysis as discussed by the authors.

Electrostatic immobilisation of copper(I) and copper(II) bis(oxazolinyl)pyridine catalysts on silica: application to the synthesis of propargylamines via direct addition of terminal alkynes to imines
TL;DR: In this paper, the catalytic activity of the immobilized catalysts in the direct addition of terminal alkynes to imines leading to propargylamines was investigated under a variety of reaction conditions.
