Cascade Reactions Catalyzed by Metal Organic Frameworks

ChemSusChem, 2014
AbstractCascade or tandem reactions where two or more individual reactions are carried out in one pot constitute a clear example of process intensification, targeting the maximization of spatial and temporal productivity with mobilization of minimum resources.

An enzyme-triggered enantio-convergent cascade-reaction

Tetrahedron: Asymmetry, 2001
Abstract The biocatalytic hydrolysis of the (±)-2,3-disubstituted cis -chloroalkyl epoxides 1a and 2a using resting cells of Rhodococcus sp. did not give the corresponding chloroalkyl vic -diols 1b , and 2b , respectively, but furnished the rearranged products (2 R ,3 R )- 1c and (2 R ,3 R )- 2c in high e.e.

Hydrazone‐Initiated Reaction Cascades

Asian Journal of Organic Chemistry, 2016
AbstractIn this Focus Review, recently reported cascade reactions that are initiated from hydrazones are described. These cascades are grouped based on the mechanistic characteristics of the reactions paired with the hydrazone‐based transformations. Reactions in which the hydrazone simply acts as a surrogate for a diazo group are not discussed, but ...

Epinephrine: Cascade Reactions and Glycogenolytic Effect

Science, 1966
The concept of a cascade reaction may serve to indicate the underlying chemical similarity between several biological amplification processes, and as a basis for the formulation of units that emphasize amplification phenomena in reaction kinetics. This approach is discussed in relation to the glycogenolytic effect of epinephrine.

2.7 Radical Cascade Reactions

2021
AbstractThis chapter briefly summarizes the concept of radical cascade reactions (RCR). The chapter is divided into two main parts, describing intramolecular and intermolecular radical cascade reactions, which are further classified based on the six types of relay manner (intramolecular RCR) and six commonly used relay molecules (intermolecular RCR ...

Transformational leadership: a cascading chain reaction

Journal of Nursing Management, 2005
Historical influences still permeate contemporary nursing practise. These are mirrored in organizational philosophies, transactional and autocratic leadership styles and disempowered staff. Whilst there is disparity amongst the theorists' definitions of leadership, there is consensus pertaining to the attributes necessary to realize effective ...

Reaction cascade modifies proteins

C&EN Global Enterprise, 2019
Chemically modifying proteins with imaging probes or nonnatural amino acids can be a powerful way to study biological processes. But existing methods for introducing modifications work only at high reactant concentrations and can leave unwanted amino acid “scars.” A new method developed by Tom W.

Sulfonylative Cascade Reactions

The sulfonyl group is present in many important pharmaceuticals and agrochemicals. Methods for its installation – sulfonylation reactions – are therefore a subject of persistent synthetic interest. This work explores the process of sulfonylation itself, and its ability to mediate complex cascade reactions under both polar and radical regimes.
