Dirhodium-catalyzed C-H arene amination using hydroxylamines

Primary and N-alkyl arylamine motifs are key functional groups in pharmaceuticals, agrochemicals, and functional materials, as well as in bioactive natural products. However, there is a dearth of generally applicablemethods for the direct replacement of aryl hydrogens with NH2/NH(alkyl) moieties. Here, we present a mild dirhodium-catalyzed C-H amination for conversion of structurally diverse monocyclic and fused aromatics to the corresponding primary and N-alkyl arylamines using NH2/NH(alkyl)-O-(sulfonyl)hydroxylamines as aminating agents; the relatively weak RSO2O-N bond functions as an internal oxidant. The methodology is operationally simple, scalable, and fast at or below ambient temperature, furnishing arylamines in moderate-to-good yields and with good regioselectivity. It can be readily extended to the synthesis of fused N-heterocycles.

Discovery of imidazopyridazines as potent Pim-1/2 kinase inhibitors

High levels of Pim expression have been implicated in several hematopoietic and solid tumor cancers, suggesting that inhibition of Pim signaling could provide patients with therapeutic benefit. Herein, we describe our progress towards this goal using a screening hit (rac-1) as a starting point. Modification of the indazole ring resulted in the discovery of a series of imidazopyridazine-based Pim inhibitors exemplified by compound 22m, which was found to be a subnanomolar inhibitor of the Pim-1 and Pim-2 isoforms (IC50values of 0.024?nM and 0.095?nM, respectively) and to potently inhibit the phosphorylation of BAD in a cell line that expresses high levels of all Pim isoforms, KMS-12-BM (IC50?=?28?nM). Profiling of Pim-1 and Pim-2 expression levels in a panel of multiple myeloma cell lines and correlation of these data with the potency of compound 22m in a proliferation assay suggests that Pim-2 inhibition would be advantageous for this indication.

Pyridazines. Part 25: Efficient and selective deprotection of pharmacologically useful 2-MOM-pyridazinones using Lewis acids

An efficient and selective procedure for the cleavage of a methoxymethyl group at the 2-position in acid-sensitive pyridazinones is presented. Deprotection with Lewis acids (boron tribromide or aluminium chloride) affords 3(2H)-pyridazinones under mild conditions without affecting multiple bonds in substituents.

Chelation versus cyclometalation in a cationic Dppn-RhI complex – A unique rearrangement of norbornadiene via C-H activation of the pyridazine ring

The tetradentate ligand 3,6-bis(2-pyridyl)pyridazine (dppn) was treated with cationic RhI precursors. The mononuclear complexes [Rh(dppn)(NBD)]BF4 (1) and [Rh(dppn)(COD)]BF4 (5) were obtained in quantitative yield when treating dppn with [Rh(NBD)2]BF4 or [Rh(COD)2]BF4 respectively. Treatment of 1 with a second equivalent of the metal precursor [Rh(NBD)(CH3CN)2]BF4 led to the dinuclear complex [Rh2(dppn-H)(NBD)(eta-C7H9) (CH3CN)2](BF4)2 (2) [dppn-H = mu-C4HN2(C5H4N)2-3, 6], a mixed RhI-RhIII complex. This complex arises from C-H activation of the pyridazine ring, followed by a unique rearrangement of the NBD ligand. Compound 2 was also obtained directly by treating dppn with 2 equiv. of [Rh(NBD)(CH3CN)2]BF4. The complex [Rh2(dppn-H)(NBD)(eta1-C7H9) (CH3OH)2(CH3CN)](BF4)2 (4) was obtained by dissolving 2 in methanol. Full characterization of compounds 1, 4 and 5 included an investigation by 1H-15N GHMBC NMR spectroscopy and single-crystal X-ray structures of 1 and 4.

Clastogenicity of quinoline derivatives tested by micronucleus induction in vivo in the hepatocytes of partially hepatectomized mice

The induction of micronucleated liver cells (MN-liver cell) was examined with halogenated and hydroxylated quinolines using partially hepatectomized mice. Among the chloroquinolines, 8-chloroquinoline demonstrated a significantly higher level of induction than the control. All the fluorinated derivatives examined, except for 6-fluoroquinoline, induced significantly higher levels, and there were no appreciable differences in MN-liver cell induction among the fluorinated quinolines, regardless of their mutagenic potencies in the Ames test. Of the hydroxylated quinolines examined, 2- and 4-isomers, which are not mutagenic, induced MN-liver cells to the same extent as a mutagenic isomer, 8-hydroxyquinoline. It seems that clastogenicity was not satisfactorily correlated with mutagenicity in the Ames test as far as this class of compounds is concerned.
