The reduction of a diphenyl α-iminoketone with samarium diiodide has been studied. A fast two-electron transfer gives a samarium (Z)-enamidolate, which is protonated to afford an α-aminoketone or reacted with a variety of ketones to furnish pyrrole derivatives. Possible mechanisms are proposed.
已经研究了用二碘化sa还原二苯基α-亚氨基酮。快速的两电子转移产生gives(Z)-en烯酸酯,将其质子化以提供α-氨基酮或与多种酮反应以提供吡咯衍生物。提出了可能的机制。
