Tetrazoles via Multicomponent Reactions [PDF]
Chemical Reviews, 2019 Tetrazole derivatives are a prime class of heterocycles, very important to medicinal chemistry and drug design due to not only their bioisosterism to carboxylic acid and amide moieties but also to their metabolic stability and other beneficial ...

Active Methylene-based Multicomponent Reactions under Microwave Heating [PDF]
CHIMIA, 2011 The use of emerging multicomponent reactions (MCRs) in conjunction with microwave (MW)-assisted chemistry techniques is dramatically reducing chemical waste and reaction times in several organic syntheses and chemical transformations.

Multicomponent reactions: A simple and efficient route to heterocyclic phosphonates
Beilstein Journal of Organic Chemistry, 2016 Multicomponent reactions (MCRs) are one of the most important processes for the preparation of highly functionalized organic compounds in modern synthetic chemistry. As shown in this review, they play an important role in organophosphorus chemistry where

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 ...

Silver and gold-catalyzed multicomponent reactions [PDF]
Beilstein Journal of Organic Chemistry, 2014 Silver and gold salts and complexes mainly act as soft and carbophilic Lewis acids even if their use as σ-activators has been rarely reported. Recently, transformations involving Au(I)/Au(III)-redox catalytic systems have been reported in the literature.

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
