Fluorine Effects on Group Migration via a Rhodium(V) Nitrenoid Intermediate
Wang, Cheng-Qiang,Zhang, Yu,Feng, Chao
, p. 14918 - 14922 (2017)
An unprecedented rhodium(III)-catalyzed hydroarylation of α,α-difluoromethylene alkynes with N-pivaloxyl aroylamides through sequential C?H activation and aryl migration is detailed herein. A large array of α,α-difluoromethylene alkynes and N-pivaloxyl aryl amides were amenable to this transformation, thus providing a novel synthetic protocol for the construction of difluorinated 2-alkenyl aniline derivatives in high yields and with excellent regioselectivity. Notably, unique fluorine effects were found to underlie the thus unconventional reaction manifold.

CYP24A1 (25-hydroxyvitamin D-24-hydroxylase) is a useful enzyme target for a range of medical conditions including cancer, cardiovascular and autoimmune disease, which show elevated CYP24A1 levels and corresponding reduction of calcitriol (the biologically active form of vitamin D). A series of (E)-N-(2-(1H-imidazol-1-yl)-2-(phenylethyl)-3/4-styrylbenzamides have been synthesised using an efficient synthetic route and shown to be potent inhibitors of CYP24A1 (IC50 0.11–0.35?μM) compared with the standard ketoconazole. Molecular modelling using our CYP24A1 homology model showed the inhibitors to fill the hydrophobic binding site, forming key transition metal interaction between the imidazole nitrogen and the haem Fe3+ and multiple interactions with the active site amino acid residues.
De-novo designed library of benzoylureas as inhibitors of BCL-X L: Synthesis, structural and biochemical characterization

The prosurvival BCL-2 proteins are attractive yet challenging targets for medicinal chemists. Their involvement in the initiation and progression of many, if not all, tumors makes them prime targets for developing new anticancer therapies. We present our approach based on de novo structure-based drug design. Using known structural information from complexes engaging opposing members of the BCL-2 family of proteins, we designed peptidomimetic compounds using a benzoylurea scaffold to reproduce key interactions between these proteins. A library stemming from the initial de novo designed scaffold led to the discovery of ligands with low micromolar potency (KD = 4 μM) and selectivity for BCL-XL. These compounds bind in the canonical BH3 binding groove in a binding mode distinct from previously known BCL-2 inhibitors. The results of our study provide insight into the design of a new class of antagonists targeting a challenging class of protein-protein interactions.

, p. 1901 - 1904 (2007/10/03)
Functionalized arylmagnesium reagents bearing an ester, cyano, nonaflate or trialkylsilyloxy group undergo fast cross-coupling reactions with alkenyl iodides or bromides in the presence of catalytic amounts of Fe(acac)3 (5 mol%) at-20 °C within
Palladium-Catalyzed Reactions of Acrylic Acid and Styrene with Aryl Halides in Water
Bumagin, N. A.,Bykov, V. V.,Beletskaya, I. P.
, p. 439 - 444 (2007/10/03)
New convenient versions of the Heck reaction in water were proposed for preparation of substituted cinnamic acids and stilbene.Arylation of acrylic acid with aryl halides was effected with palladium PdX2 or palladium black as catalysts in the presence of Na2CO3.To arylate styrene in water it is necessary to use palladium complexes with tris(o-tolyl)phosphine ligands, K2CO3, and small amounts of Bu4NBr or DMF.
