Phenoxy thiazole derivatives as potent and selective acetyl-CoA carboxylase 2 inhibitors: Modulation of isozyme selectivity by incorporation of phenyl ring substituents
摘要:
A phenyl ring substitution strategy was employed to optimize the ACC2 potency and selectivity profiles of a recently discovered phenoxy thiazolyl series of acetyl-CoA carboxylase inhibitors. Ring substituents were shown to dramatically affect isozyme selectivity. Modifications that generally impart high levels of ACC2 selectivity (> 3000-fold) while maintaining excellent ACC2 potency (IC(50)s similar to 9-20 nM) were identified. (c) 2007 Elsevier Ltd.

enantioselectivity of the products. Also, several chiral ligands for Sharpless asymmetric oxidation reaction were evaluated to improve the enantioselectivity. Graphic abstract High enantioselectivity of ortho-alkoxy aryl chiral sulfoxides have been achieved by Sharpless oxidation reaction using Ti(O-i-Pr)4 and diethyl tartrate under anhydrous condition. In particular, the enantioselctivity of products was influenced
A DKR scenario towards O–P coupling reaction involving an easily accessible enantiopure phenol bearing a chiral sulfinyl auxiliary and racemic H‐phosphinates. The enantiopure P‐stereogenic phosphonates bearing two different alkoxy groups are valuable precursors to reach privileged ligands such as PAMPO.

A protocol for C−H carboxylation of electron‐deficient 2‐pyridylphenols with CO2 through a Rh(II)‐catalyzed C−H bond activation under redox‐neutral conditions has been developed. A suitable phosphine ligand was crucial for this reaction. This method provided, in generally high yields, an access to a class of pyrido‐coumarins that are key structural motifs in biologically important molecules. Facile

A game of dominoes: A synthetic route to aza‐dihydrodibenzoxepines is described, through the combination of a Rh‐catalyzed arylation and a Pd‐catalyzed C‐O coupling in a single pot. For the first time, the ability to incorporate a chiral and an achiralligand in a two‐component, two‐metal transformation is achieved, giving the products in moderate to good yields, with excellent enantioselectivities
