Stereoselective elaboration of side chain residues in cyclopropane-containing dipeptide isosteres
摘要:
A variety of alkyl, substituted alkyl, and aryl side chain residues in cyclopropane-containing dipeptide isosteres were introduced by the highly diastereoselective (dr greater than or equal to 20:1) additions of organolithium or Grignard reagents to N, N-dimethylhydrazone 6. The resulting hydrazines were transformed into the corresponding N-Boc-protected amines with little or no stereochemical erosion. (C) 1999 Elsevier Science Ltd. All rights reserved.
