Multicomponent Reactions: “Kinderleicht” [PDF]

open access: yesJournal of Chemical Education, 2020
A demonstration experiment of the synthesis of a novel tetrazole derivative via a multicomponent reaction (Ugi tetrazole four component reaction, UT-4CR) bearing a luminol moiety and a subsequent exploitation of its chemiluminescent properties is described.

Pseudo-multicomponent reactions

open access: yesRSC 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]

open access: yesMolecules, 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]

open access: yesBeilstein 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 ...

Efficient Synthesis of Boron-Containing α-Acyloxyamide Analogs via Microwave Irradiation

open access: yesMolecules, 2013
In this report, a Passerini three-component reaction utilizing boron-containing carboxylic acids or aldehydes is discussed. The reaction was carried out in water and facilitated by the use of microwave irradiation.

Stereoselective domino assembling of five molecules: one-pot approach to $(2^\primeR^*,3S^*,4^\primeR^*)$-$2^\prime,4^\prime$-diaryl-$1^\prime,4^\prime$-dihydro-$2^\primeH $-spiro[indoline-$3,3^\prime$-pyridines]

open access: yesComptes Rendus. Chimie, 2020
A new stereoselective multicomponent reaction has been found: domino assembling of two equivalents of benzaldehyde, malononitrile, oxindole and excess of ammonium acetate in acetonitrile resulted in the formation of previously unknown $(2^\primeR^*,3S ...

Chemistry and Biology Of Multicomponent Reactions [PDF]

open access: yesChemical Reviews, 2012
Multicomponent reactions (MCRs) are one-pot reactions employing more than two starting materials, e.g. 3, 4, … 7, where most of the atoms of the starting materials are incorporated in the final product.1 Several descriptive tags are regularly attached to MCRs (Fig. 1): they are atom economic, e.g.
