Asymmetrie Synthesis, Volume 2: Stereodifferentiating Addition Reactions, Part A is concerned with asymmetric addition reactions. This volume contains chapters that cover B-H additions across carbon-carbon and carbon-oxygen double bonds; carbonyl reductions using chiral modifications of lithium aluminum hydride and chiral dihydropyridines; additions of achiral and chiral nucleophiles to chiral and achiral aldehydes and ketones; organometal additions to chiral vinylic sulfoxides; and description of imine and enamine alkylations. Chemists will find the book interesting.
