A newly improved synthesis of a dibenzodioxocinone CETP inhibitor is described. Key features of the synthetic route include a chiral ligand induced alkyl addition to aldehyde and the use of triethylborane for improved selective alkylation of brominated phenyl ring.

The present invention relates to substituted 7H-dibenzo[b,g][1,5]dioxocin-5-one-derivatives, to processes for their preparation and to their use in medicaments, in particular as inhibitors of the cholesterol ester transfer protein (CETP) for the treatment and/or prevention of cardiovascular disorders, in particular hypolipoproteinaemia, dyslipidaemias, hypertriglyceridaemias, hyperlipidaemias and arteriosclerosis.
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.
