  Reductive amination of 1,4- and 1,5-dicarbonyl compounds with (S)-valine methyl ester. Synthesis of (S)-2-phenylpyrrolidine and (S)-2-phenylpiperidine

  摘要：

  The reductive amination of 4-phenyl-4-oxobutanal and 5-phenyl-5-oxoprentanal with (S)-valine methyl ester and sodium cyanoborohydride afforded the N-substituted (S)-2-phenylpyrrolidine (88% d.e.) and (S)-2-phenylpiperidine (96% d.e.), from which the levorotatory N-H cyclic amines were obtained. On the other hand, the analogous reductive amination of simple ketones, 2,5 hexanedione, and 2,6-heptanedione was poorly selective.
