Multicomponent Reactions (MCRs) [PDF]

, 2019
Multicomponent reactions (MCRs) involving three or more components have good pot, atom and step economy. There are dozens of well-known MCRs in literature. Selective examples of newly introduced MCRs, high–order MCRs, MCRs followed by post-condensation modifications, and consecutive MCRs are presented in this chapter.

Single Solid‐State Ion Channels as Potentiometric Nanosensors

Advanced Functional Materials, EarlyView.
Single gold nanopores functionalized with mixed self‐assembled monolayers act as solid‐state ion channels for direct, selective potentiometric sensing of inorganic ions (Ag⁺). The design overcomes key miniaturization barriers of conventional ion‐selective electrodes by combining low resistivity with suppressed loss of active components, enabling robust

Advances of Ugi reaction in natural product synthesis

Green Synthesis and Catalysis
The Ugi multicomponent reaction represents a highly efficient synthetic transformation, wherein all four reactants (isocyanides, amine, aldehyde or ketone and a nucleophile) are combined in one pot under mild conditions. This reaction exhibits remarkable

Multicomponent reactions in nucleoside chemistry [PDF]

Beilstein Journal of Organic Chemistry, 2014
This review covers sixty original publications dealing with the application of multicomponent reactions (MCRs) in the synthesis of novel nucleoside analogs. The reported approaches were employed for modifications of the parent nucleoside core or for de novo construction of a nucleoside scaffold from non-nucleoside substrates.

Double-distribution-function discrete Boltzmann model for combustion

, 2015
A 2-dimensional discrete Boltzmann model for combustion is presented. Mathematically, the model is composed of two coupled discrete Boltzmann equations for two species and a phenomenological equation for chemical reaction process.

Enhancing and Stabilizing Hydrogen Catalysis Through [NiFe]‐Hydrogenase Immobilization Within Macroporous Covalent Organic Frameworks

Advanced Functional Materials, EarlyView.
[NiFe]‐hydrogenases efficiently catalyze hydrogen conversion, but their instability limits biotechnological applications. Here it is shown that encapsulating hydrogenase into hierarchical COFs with macro‐ and micropores and functionalized with sulfonic or carboxylic acid groups improves enzyme stability and electron transfer to electrodes.
