C=C reactions are highly attractive as they are additions, and thus by nature highly atom-economic. Specific topics discussed: stereoselective addition of one or more carbon or heteroatom groups across a C=C bond (e.g., dihydroxylation, hydroboration, hydroamination, conjugate addition), epoxidation, aziridination, and cyclopropanation.This volume is part of a 3-volume set: Science of Synthesis Stereoselective Synthesis Workbench EditionFurther information about Stereoselective Synthesis (including sample pages and the table of contents)
