  • Pd and Cu-MEDIATED DOMINO REACTIONS for THE
    254 Pd AND Cu-MEDIATED DOMINO REACTIONS FOR THE SYNTHESIS OF SULFUR HETEROCYCLES DOI: http://dx.medra.org/10.17374/targets.2018.21.254 Morgan Donnard,* Thomas Castanheiro and Mihaela Gulea* CNRS, University of Strasbourg, LIT UMR 7200, 67000 Strasbourg, France (e-mail: [email protected]; [email protected]) Abstract. Pd and Cu-mediated domino reactions are powerful tools for the synthesis of heterocycles. In this chapter we have compiled the most relevant examples of such transformations for the synthesis of sulfur- containing heterocycles. These sequences have been organized by type of heterocycle formed and the nature of the substrates (with or without a sulfur atom). Contents 1. Introduction 2. Synthesis of heterocycles incorporating only sulfur heteroatom 2.1. From sulfur-containing starting material 2.2. From sulfur-free starting material 3. Synthesis of heterocycles incorporating one sulfur and at least another heteroatom 3.1. N,S-Heterocycles 3.1.1. From sulfur-containing starting material 3.1.2 From sulfur-free starting material 3.2 O,S-Heterocycles 3.2.1. From sulfur-containing starting material 3.2.2. From sulfur-free starting material 4. Conclusion Acknowledgements References 1. Introduction The impact of organosulfur compounds in pharmaceutical industry is significant, several sulfur- containing drugs being among the most prescribed and sold at present in the world.1 Some of them contain in their structure a sulfur heterocycle (Figure 1). Considering the continual need for the development of medicinal therapies, new S-heterocyclic compounds could lead to forthcoming pharmaceuticals. Figure 1. Structures of drugs containing a sulfur-heterocycle. 255 As a consequence, the search for new syntheses to provide original compounds of these types represents a topical subject.

BURKE CHICAGO, ILLINOIS 1932. 1. INTRODUCTION. In presenting the paper as a resume of an investigation with regards to the influence of chemicals on the selective growth of bacteria I wish to acknowledge my great indebtedness to Dr. Emil Weiss, Professor of Bacteriol~gy at Loyola Univer­ sity School of Medicine, who suggested the subject. I am also indebted to Dr. Weiss for his conatant interest and kind super­ vision of this work. This project, as a whole, is a continua­ tion of an earlier study of the same subject made by various authors and limited to a small number of chemicals.
