Reactions of highly electrophilic polyfluoro unsaturated compounds with pyrazole derivatives
摘要:
Pyrazole derivatives were hydroxyalkylated at the C4 atom by hexafluoroacetate and methyl trifluoropyruvate. The products of the hydroxyalkylation were dehydrated to the corresponding alkylidene derivatives which were reacted with nucleophiles. Dicyanoethylenes, obtained from polyfluorocarbonyl compounds, alkylated pyrazol-5-ones with the formation of pyrazolopyran derivatives.
Novel indoledione derivatives were synthesized and evaluated as long chain fatty acid elongase 6 (ELOVL6) inhibitors. Systematic optimization of an indole class of lead 1 led to the identification of potent ELOVL6 selective inhibitors. Representative inhibitor 37 showed sustained plasma exposure and good liver penetrability in mice. After oral administration, 37 potently inhibited ELOVL6 activity in the liver in mice.
