Application

Ethyl trifluoroacetate can be used:
  • To synthesize cyclopentenones or furans containing trifluoromethyl group from aromatic ynones.
  • In the selective trifluoroacetylation of anilines catalyzed by 4-dimethylaminopyridine.
  • As a starting material in the two-step electrosynthesis of trifluoroacetyltrimethylsilane (CF3COSiMe3).
  • In the preparation of trifluoromethyl ketones via trifluoroacetic ester/ketone metathesis with alkyl aryl ketones.
  • To synthesize o-fluorinated trifluoro acetophenones from substituted fluorobenzene.

Uridine 5'-diphosphate N-acetylglucosamine (UDP-GlcNAc) is a natural UDP-monosaccharide donor for bacterial glycosyltransferases, while uridine 5'-diphosphate N-trifluoacetyl glucosamine (UDP-GlcNTFA) is its synthetic mimic. The chemoenzymatic synthesis of UDP-GlcNAc and UDP-GlcNTFA was attempted by three recombinant enzymes. Recombinant N-acetylhexosamine 1-kinase was used

Targeting cyclooxygenase-2 (COX-2) for molecular imaging is an attractive approach applicable for its overexpression in inflammation and many malignancies. Herein, for monitoring COX-2, we synthesize a specific COX-2 probe celecoxib-MPA probe (CMP), based on celecoxib and a water-soluble near-infrared dye
