  Synthesis of a Series of 4-(Arylethynyl)-6-chloro-4-cyclopropyl-3,4-dihydroquinazolin-2(1H)-ones as Novel Non-nucleoside HIV-1 Reverse Transcriptase Inhibitors

  摘要：

  As part of an ongoing effort to prepare novel non-nucleoside inhibitors of human immunodeficiency virus type-1 (HTV-1) reverse transcriptase (RT), a series of 4-(arylethynyl)-6-chloro-4-cyclopropyl-3,4-dihydroquinazolin-2(1H)-ones 4aa-1 has been prepared. Target compounds 4a-e were synthesized via addition of various 1-lithio-2-(aryl)alkyne nucleophiles to a 1-protected-4-cyclopropylquinazolin-2(1H)-one (7), followed by deprotection. The 3-methyl compound 4aa was prepared in an analogous manner, with the 3-alkylation performed prior to deprotection. Alternatively, the target compounds 4f-1 were prepared by addition of 1-lithio-2-(trimethylsilyl)acetylene to 7, followed by deprotection and subsequent palladium-catalyzed coupling with various aryl halides, By incorporating an aryl group onto the end of the 4-acetylene functionality, the requirement for a metabolically labile 3-methyl group on the dihydroquinazolinone nucleus has been eliminated. A number of the target compounds were shown to be potent inhibitors of HTV-1 RT. Compound 4a, which had exhibited the most favorable overall biological profile, was' resolved via a four-step procedure to provide the enantiomers 13a and 13b. Compound 13a having the (-)-4(S) configuration was shown to be the active enantiomer and was selected as a candidate for further investigation.

  Compounds having a quinazolin-2-one nucleus with a substituted alkynyl or substituted alkenyl at the 4-position are described. These compounds are useful in the inhibition of HIV reverse transcriptase (including its resistant varieties), the prevention or treatment of infection by HIV and the treatment of AIDS, either as compounds, pharmaceutically acceptable salts, pharmaceutical composition ingredients, whether or not in combination with other antivirals, immunomodulators, antibiotics or vaccines. Methods of treating AIDS and methods of preventing or treating infection by HIV are also described.
