Abstract
Reactions of organomanganese compounds R1MnI (R1 = Ph, 4-MeC6H4-, Me, Bu,n-C7H15, BuC=C, PhOC), prepared from R1Li and Mnl2 in Et2O, with aldehydes MeCH(OR2)CHO (R2 = CH2Ph, CH2OMe, CH2OCH2Ph) affordthreo-alcohols MeCH(OR2)CH(OH)R1 with high diastereoselectivity. The interactions of phenylmanganese derivatives PhMnX (X = Cl, Br, I), Ph2Mn, and Ph3MnLi with 2-benzyloxypropanal were used as examples for studying the influence of reagent and solvent nature on addition diastereoselectivity.
