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-β-amino acid derivatives.
• Synthesis of (2R)-2-trifluoromethyl-2-carboxyazetidine, (R)- and (S)-trifluoromethylhomoserines from oxazolidine intermediate obtained by condensing (R)-phenylglycinol with ETFAA.
