Description

MilliporeSigma Sigma Organics products encompass a wide range of quality reagents, solvents, catalysts, and building blocks for organic synthesis. From benchtop discovery to process development and scale-up, Sigma Organics solutions are built to meet the needs of synthetic chemists.

  • Ethyl 4,4,4-trifluoroacetoacetate (etfaa) is a general reagent to synthesize enantiopure trifluoromethyl-functionalized products. applications include:
  • Synthesis of (s)- and (r)-α-trifluoromethyl-aspartic acid and α- trifluoromethyl-serine from chiral cf3-oxazolidines, which is derived from etfaa
  • Enantiopure synthesis of trifluoromethyl-α-amino acid derivatives
  • Synthesis of (2r)-2-trifluoromethyl-2-carboxyazetidine, (r)- and (s)-trifluoromethylhomoserines from oxazolidine intermediate obtained by condensing (r)-phenylglycinol with etfaa
