Thomas Catholic University of Louvain University of Manchester Louvain la Neuve, Belgium Manchester, UK Preface Heterocyclic derivatives are important in organic chemistry as products (including natural) and/or useful tools in the construction of more complicated molecular entities. Their utilization in polymeric, medicinal and agricultural chemistry is widely documented. Dyestuff, electronic, and tanning structures, as well as life molecules frequently involve heterocyclic rings that play an important role in several chemical and biochemical processes. Volume 17 (2013) keeps the international standard of TARGETS IN HETEROCYCLIC SYSTEMS – Chemistry and Properties (THS) series and contains eight chapters, covering the synthesis, reactivity, and activity (including medicinal) of different heterorings. Authors from Canada, France, Italy, Spain, and Ukraine are present in this book. As yet, THS Volumes 1-17 published 229 reviews by 646 authors from 30 different countries for a total of about 7.000 pages. Comprehensive Reviews reporting the overall state of the art on wide fields as well as personal Accounts highlighting significative advances by research groups dealing with their specific themes have been solicited from leading Authors. The submission of articles having the above-mentioned aims and concerning highly specialistic topics is strongly urged. The publication of Chapters in THS is free of charge. Firstly a brief layout of the contribution proposed, and then the subsequent manuscript, may be forwarded either to a Member of the Editorial Board or to one of the Editors. The Authors, who contributed most competently to the realization of this Volume, and the Referees, who cooperated unselfishly (often with great patience) spending valuable attention and time in the review of the manuscripts, are gratefully acknowledged. The Editors thank very much Dr. Lucia De Crescentini for her precious help in the editorial revision of the book. Orazio A.
