Like its three successful predecessors, 'Organic Synthesis Highlights IV' allows an exciting yet brief survey of modern synthetic methods. More than 40 articles – short, precise and topical – give an overview of the most recent developments and trends in the field. Readers will learn about the key synthetic strategies, new effective methods in enantioselective catalysis, transition metal catalyzed reactions and stereoselective synthesis and applications for the synthesis of natural and non-natural products that are important for their daily work. Much emphasis is placed on referencing in order to make the primary literature easily accessible. Prof. H.-G. Schmalz carefully selected the contributions with a view to creating an up-to-date and critical survey of the current state of the art in organic synthesis
