Multicomponent reactions have gained significant importance as a tool for the synthesis of a
wide variety of useful compounds, including pharmaceuticals. In this context, the multiple …

Since its first observation in 1907, ortho-quinone methide (o-QM) has occupied a strategic
place within the framework of reactive intermediates in organic synthesis. In recent years, o …

In this work, the efficiency, generality and applicability of novel Brønsted acidic ionic liquid
triethylamine-bonded sulfonic acid {[Et3N–SO3H] Cl, N, N-diethyl-N-sulfoethanammonium …

Abstract Development of new methods of heterocyclic synthesis is still a topical issue. In this
connection, the trend related to the use of highly reactive o-quinone methides for the …

NiCl2 was found to be a highly efficient and effective catalyst for the one-pot three-
component (A3) coupling of aldehydes, amines, and alkynes to produce propargylamines in …

Three-component coupling of aldehyde, indole and kojic acid has been achieved using a
catalytic amount of InCl3 under solvent free conditions to produce a novel series of 2 …
