erythro- and threo-β-Amino boranes Mes2BCHMeCHPhNHPh were synthesized by the reaction of Mes2BCHMeLi with N-benzylideneaniline. The stereochemistry was determined by chemical derivation into the corresponding cycic carbanates via β-amino alcohols. Their thermolysis gave a mixture of the corresponding (E)-enamine and its tautomer, (E)-imine, in sharp contrast to that of β-hydroxy boranes giving the olefins.
通过 Mes2BCHMeLi 与 N-benzylideneaniline 的反应,合成了红-和三β-氨基硼烷 Mes2BCHMeCHPhNHPh。其立体化学性质是通过 β-氨基醇化学衍生成相应的环状碳酸酯而确定的。它们的热解产物是相应的(E)-烯胺及其同分异构体(E)-亚胺的混合物,这与生成烯烃的 β-羟基硼烷的热解产物形成鲜明对比。
