Chiral molecules containing asymmetric carbon centers bonded with nitrogen are ubiquitous
in nature and also form important structural fragments in both natural and man-made …

There is a need for the preparation of enantiomerically pure compounds for various
applications. An efficient approach to achieve this goal is asymmetric catalysis. The chiral …

Increased demand for more sustainable materials and chemical processes has
tremendously advanced the use of polysaccharides, which are natural biopolymers, in …

This article reviews the applications of cinchona alkaloids as asymmetric catalysts. In the last
few years, characterized by the resurgence of interest in asymmetric organocatalysis …

The classical Henry reaction, the coupling of a nitroalkane with a carbonyl compound in the
presence of a base, is an important C–C bond forming reaction in organic chemistry giving β …

The development of highly enantioselective and general catalytic nitroaldol (Henry)
reactions with ketones is a challenging yet desirable task in organic synthesis. In this …

The development of highly efficient and enantioselective heterogeneous catalysts based on
earth-abundant elements and inexpensive chiral ligands is essential for environment …

Catalyst‐controlled enantioselective nitroaldol (or Henry) reactions are presented. These
reactions represent powerful C–C bond‐forming tools and the resulting nitro alcohol …

Zinc is the 24th most abundant element in the Earth's crust. Since the discovery of pure zinc
metal in the 18th century, the main application of zinc metal is as materials. Because zinc …

Enantioselectivity values represent relative rate measurements that are sensitive to the
structural features of the substrates and catalysts interacting to produce them. Therefore …
