应用

Organocatalyst used for:

  • Direct asymmetric aldol reactions between acetone and aldehydes yielding β -hydroxy ketone and for synthesizing 1,1,1-trichloro-2-alkanols
  • Mannich reactions for synthesis fo α -amino acids and generation of 1,4-diamines
  • Conjugate additions of malonates to enones

( S)-(?)-5-(2-Pyrrolidinyl)-1 H-tetrazole can be used as an organocatalyst:
  • To prepare enantioselective chiral 1,2-oxazines from achiral ketones via an intramolecular Wittig reaction.
  • To synthesize diastereoselective Michael addition products by addition of aliphatic aldehydes to β-nitrostyrene.
  • In the direct asymmetric α-fluorination of linear and branched aldehydes usingN-fluorobenzenesulfonamide as the fluorinating agent.
