The Tetrahedron Symposia are the major international annual meetings and information points for reporting advances in organic, bioorganic & medicinal chemistry. The intention of the 17th Symposium is to bring together some of the major leaders in the field, to provide an intimate and relaxed environment, and to stimulate fresh thinking and creative ideas in those scientific fields impacting so importantly on the life and medical sciences. Unlike many meetings there is only a single session running at any time. This allows for clarity of focus by the participants. Leading international experts will lead a topical programme supplemented by selected contributed oral presentations and a comprehensive poster session.
