- A Well-Defined Aluminum-Based Lewis Acid as an Effective Catalyst for Diels–Alder Transformations
Zhizhou Liu, Jazreen Hui Qi Lee, Dr. Rakesh Ganguly and Dr. Dragoslav Vidović

Better Diels for Al concerned: A β-diketiminate-supported aluminum-based Lewis acid system has been created as an effective Diels–Alder catalyst. Single crystal X-ray analysis reveals a unique solid-state structure for the system. When used as a catalyst in the investigated Diels–Alder transformation, this compound is shown to be more robust than the recently reported silylium ion.
- Nickel-Catalyzed Insertion of Alkynes and Electron-Deficient Olefins into Unactivated sp3 CH Bonds

Unactive duty: A wide variety of functionalized alkynes and electron-deficient olefins have been incorporated into the unactivated sp3 CH bond of pivalic acid derivatives with excellent syn- and linear- selectivity. A strongly chelating 8-aminoquinoline directing group proved beneficial for these insertion reactions, while an air-stable and inexpensive NiII salt was used as the active catalyst. EWG=electron-withdrawing group.
- Asymmetric Synthesis of Fluorinated Isoindolinones through Palladium-Catalyzed Carbonylative Amination of Enantioenriched Benzylic Carbamates
Dr. Pablo Barrio, Ignacio Ibáñez, Lidia Herrera, Dr. Raquel Román, Dr. Silvia Catalán and Prof. Dr. Santos Fustero
Article first published online: 29 JUN 2015 | DOI: 10.1002/chem.201500773
Basic space: The asymmetric synthesis of fluorinated isoindolinones has been achieved by a palladium-catalyzed aminocarbonylation reaction of the corresponding α-fluoroalkyl o-iodobenzylamines (see figure). A base-mediated anti β-hydride elimination process was suggested to explain the partial erosion of the optical purity observed in some cases. This mechanistic rationale enabled the minimization of this partial racemization by fine-tuning the pKa of the base.
- Facile Interchange of 3d and 4f Ions in Single-Molecule Magnets: Stepwise Assembly of [Mn4], [Mn3Ln] and [Mn2Ln2] Cages within Calixarene Scaffolds
Dr. Maria A. Palacios, Dr. Ross McLellan, Dr. Christine M. Beavers, Dr. Simon J. Teat, Dr. Høgni Weihe, Dr. Stergios Piligkos, Dr. Scott J. Dalgarno and Prof. Euan K. Brechin

The central MnII ions in a series of calixarene-supported butterflies can be sequentially replaced with LnIII ions, systematically transforming the magnetic properties. This study highlights: 1) the importance of exchange over single-ion anisotropy for the observation of SMM behaviour in this family of complexes, and 2) the potential of using metalloligands to encapsulate a range of different ‘guests’ within structurally robust ‘hosts’.
- MgI2-Mediated Chemoselective Cleavage of Protecting Groups: An Alternative to Conventional Deprotection Methodologies
Mathéo Berthet, Florian Davanier, Dr. Gilles Dujardin, Prof. Jean Martinez and Dr. Isabelle Parrot
Article first published online: 29 JUN 2015 | DOI: 10.1002/chem.201501799
Amazing MgI2: Protecting groups have had a tremendous positive impact on the art of biomolecule synthesis. In a context in which the use of attractive protecting groups is often limited by harsh deprotection conditions and low chemoselective flexibility, MgI2 offers, by the execution of a very simple protocol, a fresh vision with extensive perspectives.
