Carbon-l3 NMR of Flavonoids, Studies in Organic Chemistry, 39, edited by PK Agrawal. Elsevier Science Publishers, Amsterdam, 1989. pp 564, US$l84.25, Dfl350.00

The series of books entitled Studies in Natural Products Chemistrv under the editorship of Professor Atta-ur-Rahman brings together information from diverse fields of nhvsical and biomedical sciences. Each volume has a central theme as a iin& of the various contributed chapters written by renowned scientists. The exciting advances achieved in the area of stereoselective synthesis in recent years are illustrated by the applications to natural product chemistry presented in this book. The third volume to be devoted to this topic, it contains contributions by many eminent chemists and describes the stereosecletive and enantioselective approaches to a variety of complex and challenging natural products.

This detailed treatise is written for chemists who are not NMR soectroscopists but who wish to use carbon-13 NMR spectroscopy. It shows why measurement of carbon-13 NMR is needed and exulains how the method can - or should - be used for rapid characterizafion of flavonoids, one of the most diverse and widespread groups of natural constituents. The first part of the book presents background information and discussion of the essential asuects of flavonoids and carbon-13 NMR sDectroscopy and demonstrates its significant role in the revision of’several earlier established chemical structures. It discusses various one- and two-dimensional NMR spectroscopic techniques and other relevant experimental methodologies for the interpretation of spectral details which enable individual resonance lines to be associated with the appropriate carbons in a molecule. The second Dart provides a comprehensive coverage of the carbon-13 chemical shifts of various classe’s and subclasses of flavotioids. It also illustrates how to utilize carbon-13 data to gain information for the determination of the nature, number and site of any substituent in flavonoids. Vital information for the differential and complete structure elucidation of the various classes of flavonoids by carbon-13 NMR shielding data is described in depth in the third part of the book. The book will be welcomed by all those working in natural product chemistry who will appreciate the non-mathematical approach and the fact that such a wealth of theoretical and practical information has been assembled in a single volume.

Vol 5, Structure Elucidation Dfl500.00

(Part B), 1989. xii + pp 906, US$244.00,

This book, the fifth in the series Studies in Natural Products Chemistry, is the second covering structure elucidation of new natural products. It deals with the applications of modem spectroscopic techniques with particular reference to biologically important natural products including coumarinolignans, flavonoids, f&an&apththoquin&es, antimalarial; (en artemisinin), quassinoids, triterpenes, isoquinoline alkaloids, indole alkaloids, insect iheromones, pol$saccharid& from fungi and ‘lichens and marine natural products. Other areas covered are those involving studies of carcinogenicity of estrogens, lignans biosynthesis, oligo (Nmethylpyrrolecarboxamide)antibiotics, polyketide antibiotics, antitumor, antifungal and herbicidal antibiotics, sterols, carotane sesquiterpenes, sesquiterpene quinones, prostaglandin synthetase inhibitors and avian hemoglobins. The authoritative articles from leading natural product chemists should provide a wealth of informative material for research work in this field. Vo16, Stereoselective Synthesis (Part D), 1990. x + pp 606, US$lS9.75, Dfl370.00 The present volume is the sixth in this series, and the fourth devoted to stereoselective synthesis. The articles included in the book cover the synthetic approaches to marine terpenoids, allenic and acetylenic carotenoids, gibberellins, antheridiogens, fungal metabolites, macrocycle antibiotics, sugar analogues, peptidoglycan analogues, chemical defense agents in ants, medium sized ring heterocvcles. Strvchnos alkaloids. sgmiochemicals and bioregulatorsy The auihoritativk reviews are ali written by distinguished scientists and will undoubtedly prove to be informative and interesting. Advanced EPR, Applications in Biology and Biochemistry, edited by AJ Hoff. Elsevier Science Publishers, Amsterdam, 1989. xxiv f pp 918, US$248.75, Dfl510.00

This new book provides an up-to-date survey of existing EPR techniques and their applications in biology and biochemistry, and also provides a wealth of ideas for future develouments in instrumentation and theorv. The material is broadly organized into four parts. In the first p&t (chauters 1 to 6) pulsed EPR is discussed in detail. The second Dart (chapters 7 to 12j irovides detailed discussions of a number of novefand experimental methods. The third part comprises seven chapters on double-resonance techniques, five on ENDOR and two on optically- and reaction yield-detected resonance. The final part is devoted to a thorough discussion of a number of new developments in the application of EPR to various biological and biochemical problems.

Elsevier Science Publishers, Amsterdam, 1989. xxii + pp 626, US$ 294.75, Dfl 560.00; subscr. price: US$ 268.50, Dfl Sl?.OO The publication of this volume is another step in the supplementation of the second edition of Rodd’s Chemistry of Carbon Compounds, thus keeping this major work of reference up-to-date. This supplement covers chanters 48-56 inclusive of the second edition. It covers what may be described as a “heterogeneous collection of heterocycles”. Compounds reviewed range from organometallics to physiologically active compounds such as the benzodioxapines and macrolide antibiotics, from the commerciallv important caurolactam to the svnthetically useful crown ethers and iheopetically intkresting heteroannilenes. Although the chapters in this book stand on their own, it is intended that they should be read in conjunction with the parent chapter in the second edition.
