  Dibenzodioxocinones—A new class of CETP inhibitors

  摘要：

  Derivatives of the natural product 11-hydroxy-3-[(S)-1-hydroxy-3-methylbutyl]-4-methoxy-9-methyl-5H,7H-dibenzo[b,g][1,5]dioxocin-5-one 1 were studied as novel CETP inhibitors. Compound 2 was identified from HTS as a micromolar inhibitor. The compound suffered from very low stability in plasma. Optimisation by partial synthesis started from 1 and led to low-nanomolar inhibitors with good stability in rat plasma. (c) 2005 Elsevier Ltd. All rights reserved.

  Abstractmagnified imageAn efficient and chemoselective palladium‐catalyzed direct B‐alkyl Suzuki–Miyaura cross‐coupling of trialkylboranes with diversely functionalized aryl bromides is described. A wide variety of unmasked acidic or basic functions are tolerated. The mild non‐aqueous conditions are compatible with aldehydes, ketones, nitriles, chloro substitution as well as base‐labile phenolic Piv and TBS protecting groups. The anhydrous conditions were found to be advantageous for aryl bromide substrates. A potent CEPT inhibitor was efficiently synthesised using this protocol.
