This review covers 2012 literature on the synthesis chalcogens, namely, thiophenes, selenophenes, and tellurophenes. Accordingly, the synthesis of the parent rings of these chalcogens was prepared by catalyzed electrocyclic cyclization, Dieckmann-type cyclization, Gewald reaction, organic cascade, and domino cyclization reactions. Elaboration of the chalcogens involved: direct CH arylation, cyanation, and borylation without metallic reagents, cross-coupling reactions with Pd catalysis, direct carboxylation, and enantioselective organocatalyzed cross-aldol reactions. Further modification of the chalcogens rings includes decarbonylation, differential oxidation, and hydrodesulfurazation. Several syntheses of important polymeric and conjugated material are discussed and their possible importance in material science is highlighted. New syntheses and applications of various novel chalcogens to medicinal chemistry are emphasized.
The chapters are organized according to ring size and the type of heteroatom contained. The text is supported by clear diagrams, references and a subject index.
This is the sixteenth annual volume of Progress in Heterocyclic Chemistry, and covers the literature published during 2003 on most of the important heterocyclic ring systems. This volume opens with two specialized reviews.
Progress in Heterocyclic Chemistry Series
Progress in Heterocyclic Chemistry (PHC), Volume 30, the latest in this annual review series commissioned by the International Society of Heterocyclic Chemistry (ISHC), contains both highlights of the previous year’s literature on ...
This work reviews critically the heterocyclic literature essentially published in 1993.
The author also discusses some of his unpublished results on the topic. The second review is of an entirely new format for PHC. The President of ISHC A. Padwa describes the application of selected "Heterocycles as Vehicles for Synthesis".
