Over the last decade the environmental setup has changed for
synthetic organ ic chemists to a considerable degree. So far
synthetic organic chemistry had focussed on methodology development
which mainly deals with the develop ment of new reactions as well
as new reagents and catalysts. These ought to be able to perform
preferentially highly selective (chemo-, regio-and stereose
lective) synthetic transformations, often applied in the context of
complex and highly functionalized molecules. Except for the
synthesis of peptides and oligonucleic acids, little attention has
been spent on the question of how synthesis can be carried out in
an envi ronment of sophisticated technologies which includes
improved hardware. While peptides and oligonucleotides are
conveniently prepared by Merrifield's solid phase technique,
solution phase synthesis of most other synthetic targets have not
been substantially replaced by this solid phase approach. Without
discussing this aspect in detail it is obvious that today a
renaissance of sophis ticated solution phase synthesis can be
noted. Immobilization of reagents and particularly catalysts, an
old concept indeed, recently returned back onto the stage and this
is addressed in this volume of Topics in Current Chemistry in a
broader sense."
Carbon Rich Compounds are defined here as carbon skeletons with a
carbon to hydrogen ratio of 1:(=

This well-illustrated book highlights freshwater mussels' fabulous
diversity, amazing array of often bizarre ecological adaptations,
and their dire conservation plight. Summarizing and synthesizing
historical and contemporary information as well as original
research and analysis, the book describes the diverse array of
mussel life history strategies and builds a cohesive narrative
culminating in the development of explicit frameworks to explain
pervasive patterns in mussel ecology. The fascinating and colorful
role of mussels in human society is also described in detail,
including the little-known pearl button industry of the early 1900s
and the wild and often violent shell harvest of the 1990s. The
final chapter details humans' efforts to save these fascinating
animals and gives a prognosis for the future of the North American
fauna. The book provides the first comprehensive review of mussel
ecology and conservation for scientists, natural resource
professionals, students, and natural history enthusiasts.
