, p. 3462 - 3467 (2016/07/18)
Glycolate alkylation reactions of (S)-4-isopropyl-1-[(R)-1-phenylethyl]imidazolidin-2-one auxiliary has been optimised with high yields and diastereoselectivity on substituted benzyl and allyl bromides. The standardised reaction condition was employed for the stereoselective synthesis of EEHP and EMHP intermediates of PPAR agonists.
PPAR-SPARING COMPOUNDS FOR THE TREATMENT OF METABOLIC DISEASES
-
Paragraph 0311-0312, (2015/02/19)
The present invention relates to hydroxamate compounds and pharmaceutical compositions that are useful for treating and/or preventing metabolic inflammation mediated diseases such as diabetes, obesity, hypertension, dyslipidemia, a neurodegenerative disorder (e.g., Alzheimer's disease, Parkinson's disease, or Huntington's disease), or any combination thereof. Moreover, the present invention also provides methods of treatment for these diseases or disorders.
Efficient Synthesis of Differentiated syn-1,2-Diol Derivatives by Asymmetric Transfer Hydrogenation-Dynamic Kinetic Resolution of α-Alkoxy-Substituted β-Ketoesters
Monnereau, Laure,Cartigny, Damien,Scalone, Michelangelo,Ayad, Tahar,Ratovelomanana-Vidal, Virginie
, p. 11799 - 11806 (2015/08/11)
Asymmetric transfer hydrogenation was applied to a wide range of racemic aryl α-alkoxy-β-ketoesters in the presence of well-defined, commercially available, chiral catalyst RuII-(N-p-toluenesulfonyl-1,2-diphenylethylenediamine) and a 5:2 mixture of formic acid and triethylamine as the hydrogen source. Under these conditions, dynamic kinetic resolution was efficiently promoted to provide the corresponding syn α-alkoxy-β-hydroxyesters derived from substituted aromatic and heteroaromatic aldehydes with a high level of diastereoselectivity (diastereomeric ratio (d.r.)>99:1) and an almost perfect enantioselectivity (enantiomeric excess (ee)>99>). Additionally, after extensive screening of the reaction conditions, the use of RuII- and RhIII-tethered precatalysts extended this process to more-challenging substrates that bore alkenyl-, alkynyl-, and alkyl substituents to provide the corresponding syn α-alkoxy-β-hydroxyesters with excellent enantiocontrol (up to 99‰ee) and good to perfect diastereocontrol (d.r.>99:1). Lastly, the synthetic utility of the present protocol was demonstrated by application to the asymmetric synthesis of chiral ester ethyl (2S)-2-ethoxy-3-(4-hydroxyphenyl)-propanoate, which is an important pharmacophore in a number of peroxisome proliferator-activated receptor α/γ dual agonist advanced drug candidates used for the treatment of type-II diabetes. RuII-catalyzed asymmetric transfer hydrogenation with dynamic kinetic resolution was successfully applied to a wide variety of racemic α-alkoxy-β-ketoesters derived from substituted aromatic and heteroaromatic benzaldehydes and cinnamaldehydes (see scheme; PMB=p-methoxybenzyl, S/C=substrate/catalyst ratio).
