The inter- and intramolecular coupling of imines promoted by samarium diiodide and Lewis acids or by Zn/MsOH was extensively studied. The intramolecular reaction of chiral, enantiomerically pure bis-imines was also considered, and allowed the efficient, stereoselective synthesis of 1,2-diamines with C2-symmetry.
二碘化sa和路易斯酸或Zn / MsOH促进了亚胺的分子间和分子内偶联。还考虑了手性,对映体纯的双亚胺的分子内反应,并允许以C 2对称性有效,立体选择性地合成1,2-二胺。
