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
由 R1Li 和 Mnl2 在 Et2O 中制备的有机锰化合物 R1MnI(R1 = Ph, 4-MeC6H4-, Me, Bu,n-C7H15, BuC=C, PhOC)与醛类 MeCH(OR2)CHO (R2 = CH2Ph, CH2OMe, CH2OCH2Ph) 提供具有高非对映选择性的苏式醇 MeCH(OR2)CH(OH)R1。以苯基锰衍生物 PhMnX(X = Cl、Br、I)、Ph2Mn 和 Ph3MnLi 与 2-苄氧基丙醛的相互作用为例,研究试剂和溶剂性质对加成非对映选择性的影响。
