Supramolecular catalysis is a rapidly expanding discipline which has benefited from the
development of both homogeneous catalysis and supramolecular chemistry. The properties …

In the development of new systems for asymmetric synthesis it has always been a big
challenge to obtain optically active compounds with good yields and selectivities. For this …

This communication reports experimental and theoretical evidences of σ‐hole interactions in
adducts between nitrogen or oxygen nucleophiles and tetroxides of osmium or other group 8 …

The osmium tetroxide mediated dihydroxylation of alkenes is a basic organic reaction, and
its catalytic asymmetric form has proven to be a powerful method for enantioselective …

Chemical reaction outcomes are often rationalized on the basis of independent analyses of
steric and electronic effects. We applied three-dimensional free energy relationships …

The development of new catalytic systems for cis-dihydroxylation and epoxidation of
alkenes, based on atom economic and environmentally friendly concepts, is a major …

The Sharpless asymmetric aminohydroxylation (AA), first reported in 1996, 1 allows for the
catalytic and enantioselective synthesis of protected vicinal aminoalcohols, in a single step …

Herein, we disclose osmaelectrocatalyzed C− H activations that set the stage for
electrooxidative alkyne annulations by benzoic acids. The osmium electrocatalysis enables …

The carboxylic acid promoted cis-dihydroxylation and epoxidation of alkenes catalyzed by
[MnIV2O3 (tmtacn) 2] 2+ 1 employing H2O2 as oxidant is described. The use of carboxylic …

This report illustrates the applications of Asymmetric Sharpless Aminohydroxylation (ASAH)
in the stereoselective synthesis of vicinal amino alcohols as important intermediates in the …
