Synthesis and oxidation of all isomeric 2-(pyrazolyl)ethanols

[Figure not available: see fulltext.] An efficient approach to the preparation of N-substituted 2-(pyrazol-4-yl)ethanols based on recyclization reaction of 3-(dimethoxymethyl)-2-methoxytetrahydrofuran with hydrazines is described. Oxidation by KMnO4 led to 2-(pyrazol-4-yl)-2-oxoacetic acids. In contrast, 2-(pyrazol-5-yl)ethanol under similar conditions gave only pyrazole-5-carboxylic acid, which formed as a result of oxidation followed by decarbonylation. 2-(Pyrazol-3-yl)ethanol in this oxidation reaction gave a mixture of 2-oxo-2-(pyrazol-3-yl)acetic acid and pyrazole-3-carboxylic acid.

Room Temperature Carbonylation of (Hetero) Aryl Pentafluorobenzenesulfonates and Triflates using Palladium-Cobalt Bimetallic Catalyst: Dual Role of Cobalt Carbonyl

An efficient method for the carbonylation of (hetero) aryl pentafluorobenzenesulfonates and triflates under exceptionally mild conditions using palladium/dicobalt octacarbonyl [Pd/Co2(CO)8] has been developed. Besides acting as carbon monoxide (CO) source, Co2(CO)8enhances the reaction rate by accelerating the CO insertion through an in situ generated bimetallic palladium cobalt tetracarbonyl [Pd-Co(CO)4] complex. Under the optimized reaction condition, carbonylation of a wide range of activated and deactivated, as well as sterically hindered and heteroaromatic, substrates proceeded efficiently at room temperature. The high chemoselectivity and improved synthesis of biologically relevant Isoguvacine and Lazabemide intermediates highlights its scope as a valuable synthetic method. The generality of this protocol was further extended to other electrophiles (bromides, chlorides and tosylates). (Figure presented.).

Electrosynthesis of pyrazole-4-carboxylic acids by oxidation of 4-formylpyrazoles on NiO(OH)-electrode in aqueous alkaline solution

Electrochemical oxidation of di- and trisubstituted 4-formylpyrazoles on a Ni-anode in aqueous alkali led to the formation of the corresponding pyrazole-4-carboxylic acid in 60-90% yields. The yields of the target products depend on position of substituent in the pyrazole ring and are decreased in the following sequence of substituent at position 1 Me > Et > Ph, as well as when the aqueous medium was replaced with aqueous alcohol (50% Bu tOH). Oxidation of 4-formylpyrazoles containing Me groups at the carbon atoms of the pyrazole ring led, to monoacids and also pyrazoledicarboxylic acids in small (1.5-14%) amounts; the latter were the oxidation products of the aldehyde and the Me groups.

ortho-Substituted azoles as selective and dual inhibitors of VEGF receptors 1 and 2

We have developed a series of novel potent ortho-substituted azole derivatives active against kinases VEGFR-1 and VEGFR-2. Both specific and dual ATP-competitive inhibitors of VEGFR-2 were identified. Kinase activity and selectivity could be controlled by varying the arylamido substituents at the azole ring. The most specific molecule (17) displayed >10-fold selectivity for VEGFR-2 over VEGFR-1. Compound activities in enzymatic and cell-based assays were in the range of activities for reported clinical and development candidates (IC50 30 × 10-5 cm/min) is indicative of their potential for intestinal absorption upon oral administration.
