A Microfluidics Reaction System with Automation for a Multicomponent Reaction [PDF]
Advanced Intelligent Systems, 2020 A multicomponent reaction is established toward quinazolimine derivatives, but it requires intensive human interventions in conventional reaction systems to suppress the side reactions. Herein, an automated microfluidics‐based reaction system that uses a

Pseudo-multicomponent reactions
RSC Advances, 2023 Pseudo-MCRs are domino-type one-pot processes that involve combinations of at least three reactants (similarly to normal MCRs) but in which one of them is stoichiometrically duplicated (or more) and hence takes part into two reaction steps (or more).

Multicomponent Reactions [PDF]
Molecules, 2019 Multicomponent Reactions appear to be ideal for any form of synthesis, because of their numerous advantages in terms of sustainability and selectivity in building up complex molecular architectures, with high molecular diversity. This Special Issue collects seven contributions which expand our knowledge about Multicomponent Reactions, providing a good ...

Multicomponent reactions II [PDF]
Beilstein Journal of Organic Chemistry, 2014 The concept of multicomponent reactions (MCR) [1] has been around in organic chemistry since the very early days. Indeed, the first example known in literature, the Strecker synthesis of α-aminonitriles [2], has been developed into an industrial process for the production of methionine in an annual scale of several hundreds of thousand tons per year ...

From sequence-defined macromolecules to macromolecular pin codes [PDF]
, 2020 Dynamic sequence-defined oligomers carrying a chemically written pin code are obtained through a strategy combining multicomponent reactions with the thermoreversible addition of 1,2,4-triazoline-3,5-diones (TADs) to indole substrates.
