Marine Natural Products Chemistry

This volume contains the lectures presented at the NATO­ sponsored conference on "Marine Natural Products" held in Jersey, Channel Islands, U. K., October 12-17, 1976. The intent of the organising committee was to encourage a dialogue between organic chemists who study the metabolites of marine organisms and biolo­ gists, ecologists, and pharmacologists who study the effects of these metabolites on other organisms. A feature of the conference was the three workshop sessions on chemotaxonomy, applications of marine natural products, and chemical communication. The papers presented at the conference contain a mixture of original research in marine natural products and reviews of some of the more important subjects. The biologists were asked to present papers which could initiate new directions for marine natural products research. Their contributions to the meeting were warmly received by the chemists in the audience. We hope that this volume contains not only past and present research but a suggestion of future research trends. The conference was first suggested by Dr. E. D. Goldberg. The organising committee, Drs. G. Blunden, D. J. Faulkner, W.
