合成含氟杂环医药和农药的重要中间体，有机合成砌块。 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. |
| 产品介绍 | 溶于乙醇、醚、苯等溶剂。水中溶解度:10 g/l (20°C)。 |
