Abstract

The synthesis of a new library of polyheterocyclic 11 H -pyrido[2,1- b ]quinazolin-11-one derivatives was investigated. Satisfactory conditions were obtained via sequential C–N Buchwald–Hartwig coupling and pyridine dearomatization. In this work, traditional solvents were replaced by the bio-sourced eucalyptol, confirming the interest in it as a green solvent in chemistry. [ABSTRACT FROM AUTHOR]

2. Eucalyptol: A Bio-Based Solvent for the Synthesis of O,S,N-Heterocycles. Application to Hiyama Coupling, Cyanation, and Multicomponent Reactions

Author

Subjects
eucalyptol, sustainable chemistry, O,S,N-Heterocycles, Hiyama coupling, cyanation reaction, multicomponent reaction, Chemical technology, TP1-1185, Chemistry, QD1-999
Abstract

We report here the use of eucalyptol as a bio-based solvent for Hiyama coupling, cyanation, and multicomponent reactions on O,S,N-heterocycles. These heterocycles were chosen as targets or as starting materials given their biological potential; they play an important role in therapeutically active compounds. Once again, eucalyptol proved to be a credible and sustainable alternative to common solvents.

3. Demonstration of Green Solvent Performance on O,S,N-Heterocycles Synthesis: Metal-Free Click Chemistry and Buchwald—Hartwig Coupling

Author

Joana F. Campos, Manon Cailler, Remi Claudel, Benjamin Prot, Thierry Besson, and Sabine Berteina-Raboin

Subjects
eucalyptol, cyclopentyl methyl ether, 2-methyltetrahydrofuran, O,S,N-heterocycles, greener methodology, green solvent, Organic chemistry, QD241-441
Abstract

The development of new and greener approaches to organic synthesis has been a trend in recent years. Continuing the latest publications of our team, in this work, we demonstrate the efficiency of three solvents: eucalyptol (1,8-cineole), cyclopentyl methyl ether (CPME), and 2-methyltetrahydrofuran (2-MeTHF) for the synthesis of O,S,N-heterocyclic compounds.

4. Eucalyptol as a Bio-Based Solvent for Buchwald-Hartwig Reaction on O,S,N-Heterocycles

Author

Joana F. Campos and Sabine Berteina-Raboin

Subjects
eucalyptol, buchwald–hartwig reaction, o,s,n-heterocycles, greener methodology, bio-based solvent, Chemical technology, TP1-1185, Chemistry, QD1-999
Abstract

We report here the use of eucalyptol as a bio-based solvent for the Buchwald−Hartwig reaction on O,S,N-heterocycles. These heterocycles containing oxygen, sulfur and nitrogen were chosen as targets or as starting materials. Once again, eucalyptol demonstrated to be a possible sustainable alternative to common solvents.
