There have been many new developments in the field of conformational analysis of six-membered carbocycles and heterocycles, but the most recent literature on the subject is mainly scattered throughout research publications in different areas of chemistry. This volume reviews the new information, which is becoming increasingly important in the organic-, physical organic- and biochemistry of understanding how conformational effects govern the shapes of molecules and their intermolecular interactions. The book should be of interest to organic chemists, biochemists, stereo chemists, structural chemists and pharmaceutical chemists.

This monumental tome by Prof. Atta-ur-Rahman and Dr. Zahir Shah pres ents a broad overall perspective of stereo selectivity in the synthesis of or ganic molecules. Thus it treats a problem that is of fundamental importance and will be even more important in the future as the drug industry is required to supply 1000/0 optically pure compounds. After an exposition of general principles, the following subjects are treated: Catalytic Reductions, Heterogeneous Catalytic Hydrogenations, Stereoselective Non-Catalytic Reductions, Stereos elective Carbon-Carbon Bond Forming Reactions, Asymmetric Oxidations, Asymmetric Carbon Heteroatom Bond Formations, Enzyme Catalyzed Reactions, Stereo selective Free Radical Reactions, and finally Miscellaneous Stereoselective Reactions. For each subject, a wealth of examples are given. The highly selective reactions are mentioned along with reactions that are not. This is helpful as it will teach the practical chemist what to avoid. Much progress has been made in the last two decades in the design of new, very stereoselective reactions which can be applied in industry. For example, and in alphabetical order, we can mention (among other peers): H.C. Brown (hydroboration), D.C. Evans (carbon-carbon bond forma tion), R. Noyori (BINAP reagents for hydrogenation), and K.B. Sharpless (epoxidation and dihydroxylation of double bonds). Thus the field has completely changed since the 1950s, when optically pure compounds were always obtained by difficult resolutions of racemates and not by stereoselec tive reactions.

This monograph presents extensive tabulations of NMR chemical shifts, coupling constants, and correlations for rigid bicyclic systems related to bicyclo[2.2.1]heptane ("norbornane") and bicyclo[2.2.2]octane. These systems are useful because they are relatively fixed and allow accurate estimation of internuclear distances and bond angles. Thus, they serve as model systems for the estimation of steric and electronic substituent effects on NMR chemical shifts and coupling constants in non-rigid systems. No similar treatment of NMR data of rigid bicyclic systems has ever appeared before.

An understanding of chirality is central to the study and application of the molecular sciences. Particularly relevant to the work of pharmaceutical, natural product, organic, and analytical chemists, biochemists, and molecular biologists, Chirality in Natural and Applied Science provides a highly practical overview of the chemical significance of chirality.
Contributions from world-class scientists describe our current understanding of chirality and discuss its significant impact on modern chemistry and molecular science. They explore the origins of chirality, its natural occurrence on a variety of scales, and its current and potential applications in research and industry.
Chirality undoubtedly will remain integral to all of molecular science, and as our knowledge and understanding grow, its importance certainly will increase. Bringing together the insights and experience of scientists who have played influential roles in chirality research, Chirality in Natural and Applied Science helps ensure a thorough understanding of chirality, its importance and its applications.
