Written for phytochemists, synthetic chemists, combinatorial chemists, as well as other practitioners and students in related fields, this volume presents cutting-edge research in the chemistry of bioactive natural products and helps the reader understand how natural product research continues to make significant contributions in the discovery and development of new medicinal entities. The reference presents chemistry and pharmaceutical potential of natural products in modern drug discovery processes, and covers the synthesis and semi-synthesis of potentially bioactive natural products. It features chemical advances in naturally occurring organic compounds and describes their spectral properties, chemical transformations, and structure-activity relationships.
