Steroid diversification by multicomponent reactions [PDF]
Beilstein Journal of Organic Chemistry, 2019 Reports on structural diversification of steroids by means of multicomponent reactions (MCRs) have significantly increased over the last decade. This review covers the most relevant strategies dealing with the use of steroidal substrates in MCRs ...

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 ...

Pseudo-multicomponent reactions. [PDF]
RSC Adv, 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).

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

Multicomponent Reactions: "Kinderleicht". [PDF]
J Chem Educ, 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.

Electrochemical Synthesis of Sulfonamides in Single‐Pass Flow
ChemElectroChem, 2023 An electrochemical multicomponent synthesis of sulfonamides at room temperature in single‐pass flow is presented. In contrast to batch‐type electrolysis, an undivided flow cell setup with a stainless‐steel cathode and either a boron‐doped diamond (BDD ...
