A symposium on stereoeselective synthesis was organized by
the Schering AG to honour Professor Dr. Dr. h.c. Rudolf
Wiechert's 65th birthday and his achievements in over 30
years of successful medicinal chemistry research.
The six plenary lectures by leading scientists are published
in this book. The contributions highlight recent progress on
diastereo- and enantioselective synthesis. Intriguing
methodological work, synthesis of homochiral building blocks
and elegant and highly efficient applications to the
synthesis of stereochemically demanding targetmolecules are
presented.
