Uses

4-Ethoxy-1,1,1-trifluoro-3-buten-2-one may be used in the synthesis of 4-dialkylamino-1,1,1-trifluorobut-3-ene-2-ones. It may be used for the synthesis of β-alkyl- or dialkylamino substituted enones bearing a CF3 group.

General Description

4-Ethoxy-1,1,1-trifluoro-3-buten-2-one reacts with phenylmagnesium bromide to afford ethoxy group substitution products, while it reacts with organozinc compounds to yield products arising from 1,2-addition to the carbonyl group. 4-Ethoxy-1,1,1-trifluoro-3-buten-2-one on heating with triethyl phosphite affords [4+2] cycloaddition product, 2,2,2-triethoxy 2,3-dihydro-3-ethoxy-5-trifluoromethyl-1,2λ5-oxaphospholene, which on hydrolysis affords a 2-oxo-2-hydroxy-2, 3-dihydro-3-hydroxy 5-trifluoromethyl-1,2λ5-oxaphospholen. It reacts with amino to give the N-protected amino acids, which is useful for the peptide synthesis.

2-(Halogenated Phenyl) acetamides and propanamides as potent TRPV1 antagonists

A series consisting of 117 2-(halogenated phenyl) acetamide and propanamide analogs were investigated as TRPV1 antagonists. The structure–activity analysis targeting their three pharmacophoric regions indicated that halogenated phenyl A-region analogs exhibited a broad functional profile ranging from agonism to antagonism. Among the compounds, antagonists 28 and 92 exhibited potent antagonism toward capsaicin for hTRPV1 with Ki[CAP] = 2.6 and 6.9 nM, respectively. Further, antagonist 92 displayed promising analgesic activity in vivo in both phases of the formalin mouse pain model. A molecular modeling study of 92 indicated that the two fluoro groups in the A-region made hydrophobic interactions with the receptor.
