Abstract The development of efficient and sustainable methods for the construction of carbon-carbon bonds with the simultaneous stereoselective generation of vicinal stereogenic centers is a longstanding goal in organic chemistry. Low-valent nickel(0

In this minireview, we overview a computational pipeline developed within the framework of NCCR Catalysis that can be used to successfully reproduce the enantiomeric ratios of homogeneous catalytic reactions. At the core of this pipeline is the SCINE

N-Heterocyclic carbenes (NHCs) are the ligands of choice in a large variety of transformations entailing different transition metals. However, the number and variety of chiral NHCs suitable as stereo-controlling ligands in asymmetric catalysis remain

Asymmetric metal-catalyzed C–H functionalization is a powerful strategy for the rapid generation of complex target molecules from simple precursors. While aryl (pseudo)halides have been used as electrophilic substrates in enantioselective Pd(0)-cat

Ruthenium complexes, in particular cyclopentadienyl ruthenium (??) derivatives, catalyze a vast number of transformations in the field of homogenous catalysis. Herein we describe the first synthesis of efficient chiral cationic cyclopentadienyl ruthe

Fijiolide A is a secondary metabolite isolated from a marine-derived actinomycete of the genus Nocardiopsis. It was found to significantly reduce the TNF-? induced activity of the transcription factor NF?B, which is considered a promising target for

The activation of carbon–carbon bonds has attracted much attention in the past decade. Despite important progress, the development of asymmetric reactions lags behind. For the first time, asymmetric rhodium(I)-catalyzed direct oxidative additions i

The direct functionalization of non-activated C–H bonds, especially in an enantioselective manner, requires metal catalysts equipped with ligands with specifically designed properties. Examples for asymmetric C(sp2)–H and C(sp3)–H functionaliza
