Ligand-free-palladium-catalyzed direct 4-arylation of isoxazoles using aryl bromides

4-rylisoxazoles can be easily prepared by a palladium-catalysed C-H bond activation/arylation of 3,5-disubstituted isoxazoles using aryl or heteroaryl bromides. Good yields were generally obtained by using 0.1-0.5 mol-% of the airstable PdCl2 complex as the catalyst. A range of functional groups such as acetyl, formyl, ester, fluoro, nitro, trifluoro-methyl or nitrile on the aryl bromide is tolerated. This reaction is environmentally attractive, as the major waste is KBr/ AcOH instead of the metallic salts arising from classical cross-coupling procedures,

Discovery of BI-2545: A Novel Autotaxin Inhibitor That Significantly Reduces LPA Levels in Vivo

In an effort to find new therapeutic interventions addressing the unmet medical need of patients with idiopathic pulmonary fibrosis, we initiated a program to identify new autotaxin (ATX) inhibitors. Starting from a recently published compound (PF-8380), we identified several highly potent ATX inhibitors with improved pharmacokinetic and safety profiles. Further optimization efforts resulted in the identification of a single-digit nanomolar lead compound (BI-2545) that shows substantial lowering of LPA in vivo and is therefore considered a valuable tool for further studies.

Transformations of Modified Morita-Baylis-Hillman Adducts from Isatins Catalyzed by Lewis Bases

The development of synthetic protocols to access architectures with broad structural and functional diversity from readily available starting materials is very attractive in both organic and medicinal chemistry fields. Toward this objective, the multifunctional isatin-derived Morita-Baylis-Hillman (MBH) adducts provide opportunities to construct a variety of complex scaffolds containing a ?privileged? oxindole motif through several catalytic pathways. By forming the ammonium or phosphonium salts with Lewis bases, isatin-derived MBH adducts can undergo allylic substitutions with a range of nucleophiles, usually in a SN2?-SN2? pattern. Besides, assisted by Br¡ãnsted bases, the corresponding onium salts can be converted into the allylic ylide intermediates, which can undergo various annulation reactions or even 1,3-difunctionalizations. Moreover, recent cooperative catalysis of Lewis bases and transition metal complexes further puts forward the application of isatin-derived MBH adducts. This tutorial review covers the significant transformations of isatin-derived MBH adducts, mostly in an asymmetric version, catalyzed by various Lewis bases over the past decade.

Preparation of polyfunctional arylmagnesium, arylzinc, and benzylic zinc reagents by using magnesium in the presence of LiCl

The presence of LiCl considerably facilitates the insertion of magnesium into various aromatic and heterocyclic bromides. Several functional groups, such as -OBoc, -OTs, -Cl, -F, -CF3, -OMe, -NMe2, and -N 2NR2, are well tolerated. The presence of a cyano group leads in some cases to competitive reduction of the organic halide to the corresponding ArH compound. The presence of sensitive groups such as methyl or ethyl ester is tolerated upon in situ trapping of the intermediate magnesium reagent with ZnCl2. This method can also be applied to the preparation of functionalized benzylic zinc reagents from benzylic chlorides. In the case of di- or tribromoaryl derivatives, directing groups such as -OPiv, -OTs, -N2NR2, or -OAc orient the zinc insertion (Zn/LiCl) to the ortho-position, while the reaction with Mg/LiCl or Mg/LiCl/ZnCl 2 leads to regioselective insertion into the para-carbon-bromine bond. Large-scale experiments (20-100 mmol) for all of the metalation procedures are described.
