This work presents a definitive interpretation of the current status of and future trends in natural productsa dynamic field at the intersection of chemistry and biology concerned with isolation, identification, structure elucidation, and chemical characteristics of naturally occurring compounds such as pheromones, carbohydrates, nucleic acids, and enzymes. With more than 1,800 color figures, Comprehensive Natural Products II features 100% new material and complements rather than replaces the original work (1999). Reviews the accumulated efforts of chemical and biological research to understand living organisms and their distinctive effects on health and medicine Stimulates new ideas among the established natural products research communitywhich includes chemists, biochemists, biologists, botanists, and pharmacologists Informs and inspires students and newcomers to the field with accessible content in a range of delivery formats Includes 100% new content, with more than 6,000 figures (1/3 of these in color) and 40,000 references to the primary literature, for a thorough examination of the field Highlights new research and innovations concerning living organisms and their distinctive role in our understanding and improvement of human health, genomics, ecology/environment, and more Adds to the rich body of work that is the first edition, which will be available for the first time in a convenient online format giving researchers complete access to authoritative Natural Products content

The volumes of this classic series, now referred to simply as "Zechmeistera after its founder, L. Zechmeister, have appeared under the Springer Imprint ever since the seriesa (TM) inauguration in 1938. The volumes contain contributions on various topics related to the origin, distribution, chemistry, synthesis, biochemistry, function or use of various classes of naturally occurring substances ranging from small molecules to biopolymers. Each contribution is written by a recognized authority in his field and provides a comprehensive and up-to-date review of the topic in question. Addressed to biologists, technologists, and chemists alike, the series can be used by the expert as a source of information and literature citations and by the non-expert as a means of orientation in a rapidly developing discipline.

The dithiophenes and trithiophenes reviewed in this article are part of a large group of biogenetically related molecules found in plants of the family Compo sitae (Asteraceae). They include compounds having a variable number of unsaturations, particularly double bonds and triple bonds, which occur singly or in combinations. The first report of a naturally occurring trithiophene, ex-terthienyl in the flowers of Tagetes erecta, appeared in 1947 (270); the first naturally occurring dithiophene was isolated from Bidens radiata and described in 1961 (142). The book Naturally Occurring Acetylenes, by BOHLMANN et al. (29), is a superb review of the field up to 1972. Interestingly, out of its more than 500 pages, only two were devoted to physiological and pharmacological aspects. BOHLMANN and ZDERO later contributed one chapter, "Naturally Occurring Thiophenes," to a volume Thiophenes and its Derivatives which appeared in 1985 (57). This chapter presents a survey of such thiophenes based on biogenetic considerations, includes an extensive analysis of the distribution of these compounds, and discusses methods of analysis based on UV, lH-NMR, 13C-NMR, and mass spectra. The most recent references in the chapter came from publications appearing in 1981. In view of the information on naturally occurring dithiophenes and trithiophenes already available from these sources, this survey emphas izes the occurrence, the biosynthesis, the synthesis, the photophysical and photochemical properties, and especially the biological properties of these molecules.
