Synthetic utility of stereoselective alkylations in natural product chemistry is exemplified by the preparation of optically active 2-arylglycine esters (38). Chirally specific a-amino acids with methoxyaryl groups attached to the a-carbon were prepared by reaction of the dimethyl ether of a chiral bis-lactam derivative with methoxy arenes. Using SnCl as the Lewis acid, enantioselectivities ranging from 65 to 95% were obtained. 

Epoxide-opening iatramolecular cycli2ations, in light of their importance in natural product chemistry, have received much attention (62).

It is my opinion that this approach has considerable merit, provided that the questions posed in the problems are wisely selected, as indeed they are in this text. The authors themselves are well versed in natural-product chemistry, an area that presents a wide array of small molecule structural problems. They are therefore concerned that the reader reach the practical goal of applying the full power of NMR spectroscopy to problems of this type. To this end they have selected problems that address methods for solving structures as well as those that pertain to basic theory. The authors have wisely made a point of treating the more widely used ID and 2D experiments in considerable detail. Nevertheless, they also introduce the reader to many of the less common techniques.

Here, we will present a selection of the most attractive naturally occurring phenazines that have been newly discovered. Also, we will deal with the general methods of phenazine synthesis and its most recent applications in natural product chemistry. Until now, the relevance of Pd-catalyzed N-arylations to this...

The environmentally benign synthesis of lactones has attracted attention because of their importance in natural product chemistry. The oxidative cyclization of diols via carbon-oxygen bond formation is the most well-known approach for the synthesis of lactones [70].

The novel horizons in natural product chemistry are a consequence of advances in mass spectrometry instrumentation. Current applications comprise the elucidation of natural products as part of total extract mixtures in samples of interest to environmental chemists, archaelogists, paleobotanists, geologists, oceanographers, atmospheric chemists, forensic chemists and engineers. The list of applications is expected to expand and some examples are discussed in this chapter.
