R. Hansons book The Chemistry of Fungi presents a good overview of important natural products from fungi, dealing with their roles as antibiotics, fungicides, pigments, volatiles, plant pathogens, and mycotoxins. Therefore, the book fills a gap, since no books devoted to fungal natural products have been published in the last few years. Hanson begins with a historical retrospective, highlighting the changes in research on the isolation and structure elucidation of natural products, including those of fungi, that occurred during the last few decades through advances in chromatographic separation techniques and in instrumental analytical methods such as mass spectrometry and, first and foremost, NMR spectroscopy. In the second chapter Hanson describes the methods used to establish mycelial cultures of fungi, discusses the influences of environmental conditions and the age of the cultures on the production of secondary metabolites, and describes methods for their isolation and for the elucidation of their biosynthesis, which is a topic of great practical importance, since antibiotics are isolated on a large scale from fungal cultures. The following four chapters deal with constituents of fungi arranged according to their biogenetic origin, including amino acids, polyketides, terpenoids, and precursors of the citrate cycle. In discussing particular compounds of these classes, the author puts special emphasis on explaining the elucidation of the structures and of their biosynthesis. The chapter on fungal constituents derived from amino acids covers not only the commercially important b-lactam antibiotics, such as penicillin and cephalosporin, but also the diketopiperazines, gliotoxin, cyclopenin, cochliodinol, agaritine, and the cyclosporins that are of eminent importance in transplantation medicine because of their immunosuppressive activity. Outstanding representatives in the group of polyketides are griseofulvin, known for its ability to attack dermatophytic fungi, and the statins, highly valued for their function of depressing the cholesterol level. The chapter on fungal terpenes and terpenoids is especially detailed, including topics such as the chemistry of the trichothecenes that inhibit the sporulation of the plant-pathogenic fungus Botrytis allii, of the gibberellins that influence plant growth, and of ergosterol, which is important for the cell wall construction of fungi. That is followed by a short chapter dealing with fungal compounds that originate at least partly from the citrate cycle. These include tetronic acids, the nonadrides, and zaragozic acids. The seventh chapter is devoted to fungal pigments and volatiles. Pigments play a major role in fungi, and even a chapter devoted entirely to them can only offer a short insight into their structural diversity, as exemplified by a discussion of anthraquinone pigments, pulvinic acids, metal complexes, and carotenoids. There then follows a discussion of plant diseases caused by fungi, such as the gray mold fungus (Botrytis cinerea) that attacks more than 200 different plant species, including many crop plants and their fruits. Dutch elm disease, in which the fungus Ceratocystis ulmi is distributed from tree to tree by the elm-bark beetle, is also discussed. The penultimate chapter is devoted to the most important mycotoxins and to toxins of fruiting bodies of mushrooms. Those described include the trichothecenes, the aflatoxins, and the ergot alkaloids, as well as the amanitins and psilocybin. The last chapter deals with the application of fungal enzymes in reactions that otherwise can be accomplished only with great difficulty, such as the stereoselective hydroxylation of the CH2 group in position 11 of the steroid skeleton for the preparation of corticoids. The book provides a rich collection of information in densely packed form, focussing on terpenoids, which the author has reviewed several times in Natural Products Reports. As the number of natural products derived from fungi is so enormous, the book can only present a selection of the most important compounds. Although the properties, the structural elucidation, and the biosynthesis of many compounds are discussed, the book contains little information about chemical synthesis. The table of contents gives easy access to the natural products discussed, and a very helpful glossary explains the most important terms in fungal biology. However, this generally positive impression of the book is marred by some serious mistakes: Thus, the structural formula of amanitin is incorrect and lacks information on its absolute configuration. The typical odor of mushrooms is not caused by (S)-1- octen-3-ol but by (R)-1-octen-3-ol. A severe shortcoming is the incompleteness of the collection of references in the chapter “Further Reading”, which cites only few selected papers. That would be acceptable for a textbook, but this book is mainly intended for experienced natural products chemists, who are certainly interested in obtaining background information from original papers. Despite these deficiencies, which may be easily improved in a new edition, I recommend the book as an important source of information to all natural products chemists, as well as to biochemists, Acid Catalysis in Modern Organic Synthesis By James R.
