Hepatitis C virus inhibitors are disclosed having the general formula:(I) wherein R1, R2, R3, R', B, Y and X are described in the description. Compositions comprising the compounds and methods for using the compounds toinhibit HCV are also disclosed.
Gas-phase pyrolysis of aminomethylene Meldrum’s acidderivatives gave quinolinones and/or amines depending on the -nature of arylamino moiety. Effect of substituent on reaction rate and nature of pyrolysis products supports the suggested intramolecular nucleophilic substitution reaction via initially formed keteneamine intermediate.
Electron-rich and electron-deficient anilinomethylene derivatives of Meldrum’s acid cyclize equally efficiently to quinolin-4-ones via imidoylketene intermediates under flash vacuum pyrolysis (FVP) conditions.
