产品说明

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)-1H-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 using N-fluorobenzenesulfonamide as the fluorinating agent.
