Chemistry of Natural Products, A Unified Approach, provides a planned account of the common features structural and stereochemical of naturally occurring organic compounds). This is the only approach to bring about effective understanding of their chemistry. A variety of examples have been given to illustrate varied aspects so that the range of structure and behaviour exhibited by these compounds is retained within the set framework. The increasing application of physical (spectroscopic) methods like IR, NMR, CD, ORD, MS, High Resolution Mass Spectroscopy, using which, structural determinations are often done with very small or even microscopic quantities of the substance—is emphasised, without undermining the importance of ‘classical’ chemical methods. The section on problem solving helps to develop an analytical and critical evaluation of the data. The Second Edition reflects the significant and important developments that have taken place since the publication of the first edition, particularly with regard to the biological aspects of natural products. Unified approach: Discusses all classes of compounds. Unique approach: Discusses common structural and stereochemical features of naturally occurring organic compounds. Page extent increased by 200 pages. New chapter: Introduction. Revised Introduction for all chapters. Examples: About 100 examples across the book and 6 new per chapterCorrelation with spectral data. Problems: 5 additional problems.
