Synthesis of α‐Pentafluorosulfanylated‐β2,3‐Amino Esters

ChemistryEurope, EarlyView.
De novo α‐SF5‐β2,3‐amino esters are now accessible through a straightforward aza‐Michael reaction using a series of newly developed (E)‐α‐SF5‐α,β‐unsaturated esters. Two new, highly functionalized, contiguous tertiary stereocenters are formed with diastereodivergence governed by the choice of solvent and/or base.

Properties of epoxide hydrolase from the yeast Rhodotorula glutinis [PDF]

Epoxide hydrolases are ubiquitous enzymes that can be found in nearly all living organisms. Some of the enzymes play an important role in detoxifying xenobiotic and metabolic compounds.

Imidazoline‐Proline and Imidazoline‐Prolinate Ligands for Copper‐Catalyzed Asymmetric Exo‐Selective [3 + 2] Cycloaddition of Iminoesters with Nitroalkenes

ChemistryEurope, EarlyView.
From a modular synthesis of nonphosphine chiral nitrogen‐based chiral imidazoline–amino acid ligands, two new chiral imidazoline–proline‐copper catalysts are developed for targeting exo‐selective [3 + 2] cycloaddition reaction. Density functional theory studies rationalize the observed stereoselectivity and the distinct chiral pockets of the two ...

Well‐Defined Rhodium and Iridium Complexes Containing Chiral Cyclic(Alkyl)(Amino)Carbenes for Asymmetric Hydrogenation

ChemistryEurope, EarlyView.
A set of fourteen well‐defined rhodium and iridium complexes containing various enantiopure cyclic(alkyl)(amino)carbene (ChiCAAC) ligands (>96% ee to > 99.5% ee) has been synthesized and fully characterized. While no enantioselectivity is observed with chiral Rh‐CAAC, the Ir‐CAAC counterparts demonstrated good performances in the asymmetric ...
