  .alpha.-Lithioamine synthetic equivalents: syntheses of diastereoisomers from Boc derivatives of cyclic amines

  摘要：

  Sequences of alpha'-lithiations and electrophilic substitutions of Boc-pyrrolidines, Boc-piperidines, and Boc-hexahydroazepines that provide compounds which are substituted adjacent to nitrogen are reported, and the pathways of the reactions are discussed. By this methodology monosubstituted 2 and disubstituted 2,4,2,6, and 2,5 Boc-piperidines are obtained as single or separable diastereoisomers consistent with equatorial lithiations and retentive electrophilic substitution in chair conformations. Both cis and trans 2,6-disubstituted diastereoisomers can be prepared, and control of diastereoselectivity is demonstrated by syntheses of solenopsin A, a 2,6-trans-disubstituted piperidine, and of Boc-dihydropinidine, a 2,6-cis-disubstituted piperidine. In the case of 3-methoxy-Boc-piperidine elimination of methoxide occurs upon lithiation, and with cis-2,4-disubstituted Boc-piperidines the electrophile is introduced with trans stereochemistry at C-6. These reactions are suggested to involve twist boat conformations consistent with an X-ray crystal structure of 2-methyl-6-(trimethylstannyl)-4-phenyl-N-Boc-piperidine. Boc-pyrrolidine lithiates more rapidly than Boc-piperidine, provides 2-substituted products with electrophiles, and on further lithiation-substitution gives 2,5-cis- and -trans-substituted products. Boc-perhydroazepine provides 2-substituted products by the sequence and on further lithiation-substitution gives 2,7-trans-disubstituted products.
