  Intramolecular Cyclizations of .alpha.-Lithioamine Synthetic Equivalents: Convenient Syntheses of 3-, 5-, and 6-Membered-Ring Heterocyclic Nitrogen Compounds and Elaborations of 3-Membered Ring Systems

  摘要：

  A lithiation-intramolecular cyclization reaction of N-Boc chloroalkyl secondary amines is reported to provide the 2-aryl-substituted pyrrolidine and piperidines 6, 7, 9, and 11 and a series of 2-azabicyclo[3.1.0] derivatives 14-25, including cyclopropane derivatives of proline and of the indolizidine-pyrrolizidine alkaloid ring system. Lithiation-substitutions of N-Boc-N-ethylcyclopropylamine to give 27-29 and lithiation-silylations of N-Boc aziridines to give 31-33 also are reported.
