(好书)Topics in Current Chemistry--Stereoselective Alkene Synthesis
Preface
The stereoselective synthesis of olefins has been one of the major topics in the arena
of organic synthesis for many decades. The methods for olefin synthesis have
evolved from classic elimination reactions to more modern methods such as the
Wittig reaction and its variants, cross-coupling reactions and olefin metathesis.
Numerous reviews are available on these topics. The purpose of this special volume
is to cover the most recent advances in this ever-growing field, with a focus on
stereocontrol in C=C double formation.
Two chapters in this volume highlight the recent development of the widely used
methods for olefin synthesis, namely Wittig reactions (Chapter 7) and olefin
metathesis (Chapter 6). For olefin metathesis, the focus is put on its applications
in complex natural product synthesis. Owing to the importance of introducing
fluorine atoms to organic molecules, the methods for the stereoselective synthesis
of monofluoroalkenes have been summarized in Chapter 3. 1,3-Dienes, as a special
type of olefin, widely exist in natural products, and also find various applications in
organic synthesis. Therefore, stereoselective synthesis of 1,3-dienes is considered
as an important part of olefin synthesis. This is also included in this special volume
(Chapter 4).
Stereoselective synthesis of tetrasubstituted alkenes remains a challenging task.
A unique solution to this problem is to use torquoselectivity-controlled olefina-
tion of carbonyl compounds with ynolates, which is summarized in Chapter 1.
In general, the stereoselective synthesis of
Z
-alkenes, which are thermodynamically
less favorable, is more difficult than the synthesis of corresponding
E
-isomers.
In Chapter 2, various methods for stereoselective synthesis of
Z
-alkenes are
reviewed. Finally, the C=C double bond formation through catalytic carbene trans-
formation has recently emerged as a new approach toward olefin synthesis. Two
chapters covering olefin synthesis based on catalytic carbene transformations are
included (Chapter 5 and Chapter 8) .
Having read all the chapters, I hope that readers are left with the notion
that stereoselective olefin synthesis is still a rapidly growing area with constant
emergence of novel synthetic methods.
I would like to thank Prof. Henry N. C. Wong for his encouragement and
support, Karin Bartsch and Elizabeth Hawkins for their assistance in the whole
process. I would also like to thank the referees for their invaluable comments and
suggestions. Finally, this book would not have been possible without the partici-
pation of the authors, to whom I am deeply indebted for their enduring patience
throughout this project.
