Copper- and DMF-mediated switchable oxidative C-H cyanation and formylation of imidazo[1,2-a]pyridines using ammonium iodide

The cyanation and formylation of imidazo[1,2-a]pyridines were developed under copper-mediated oxidative conditions using ammonium iodide and DMF as a nontoxic combined cyano-group source and DMF as a formylation reagent. Mechanistic studies indicate that the cyanation of imidazo[1,2-a]pyridines proceeds through a two-step sequence: initial iodination and then cyanation. The cyanation has a broad substrate scope and high functional group tolerance, and can be safely conducted on a gram scale. A novel copper-mediated formylation using the widely available DMF as the formylation reagent and environmentally friendly molecular oxygen as the oxidant has also been developed. This protocol also provided a convenient approach for the synthesis of clinically used saripidem.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. 556-50-3, you can contact me at any time and look forward to more communication. HPLC of Formula: https://www.ambeed.com/products/556-50-3.html.

Exploring Coumarins Reduction: NaBH4/MeOH versus Nickel Boride Generated In Situ.

The role of reagents NaBH4/MeOH and nickel boride (Ni2B) generated in situ from NaBH4 and NiCl2, are compared in the reduction process of coumarin and a variety of 3,7-substituted coumarins bearing electro-donating (ED-group) or electro-withdrawing groups (EW-group). Coumarins (chromen-2-one) are only reduced with Ni2B to the cyclic chromanones. This provides a useful and very simple reduction method for electron-rich coumarins, which are resistant to many other reducing methods. DFT calculations underlined the role of substituents electronic effects in the reactivity. Subsequent methanolysis may open the ring to methyl phenylpropanoate esters and alcohols resulting from their reductions can also be produced.

An enantioselective formal synthesis of the proteasome inhibitor (+)-lactacystin

An enantioselective formal synthesis of the proteasome inhibitor (+)-lactacystim has been achieved using an alkylidene carbene 1,5-CH insertion reaction as a key step. The key cyclisation precursor was synthesised in high diastereomeric excess using a combination of known procedures, with the two key asymmetric centres being introduced via a Sharpless asymmetric epoxidation reaction. KHMDS induced 1,5-CH insertion produced a 3-pyrroline product, which was oxidised to the corresponding 3-pyrrolin-2-one using (1) TPAP/NMO; (2) NaCIO2; (3) NaBH4. The formal synthesis was then completed with a few standard functional group interconversions. (C) 2002 Published by Elsevier Science Ltd.

Design and properties of polyarylene ether nitrile copolymers with improved elongation at break

Polyarylene ether nitrile (PEN) based on biphenol exhibits a high glass transition temperature of 216 degrees C, a high tensile strength of 110 MPa, and low elongation at break of approximately 4%. A series of PEN random copolymers with improved elongation at break were synthesized using various bisphenol compounds and 2,6-dichlorobenzonitrile (DCBN). The resulting PEN random copolymers exhibited a high glass transition temperature and thermal stability up to 513 degrees C in a nitrogen atmosphere. PEN copolymers were amorphous and could easily be cast into transparent films with a tensile strength of 97.93-117.88 MPa and tensile modulus of 2187.98-2558.44 MPa. Most importantly, elongation at break of these PEN copolymers was higher than 13%. PEN copolymer films had a dielectric constant of 3.77-3.89 at 1 kHz and extremely low dielectric loss (<0.02). At the same time, the breakdown strength of PEN was in the range of 137.92-198.19 kV/mm and energy storage density was in the range of 0.32-0.68 J/cm(3). Excellent mechanical, thermal, and dielectric properties of PEN make it possible to use them as high-temperature resistant dielectrics to act on high-temperature resistant insulated cables. The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules.

Synthesis of Unsymmetrical 3,4-Diaryl-3-pyrrolin-2-ones Utilizing Pyrrole Weinreb Amides

A regiocontrolled synthesis of unsymmetrical 3,4-diaryl-3-pyrrolin-2-ones has been achieved in three steps from 1,2-diaryl-1-nitroethenes with pyrrole-2-carboxamides (pyrrole Weinreb amides) serving as the key linchpin intermediates. Two different methods for the preparation of the requisite nitroalkenes were investigated: (1) modified Henry reaction between arylnitromethanes and arylimines; and (2) Suzuki-Miyaura cross-coupling reaction of 2-aryl-1-bromo-1-nitroethenes with arylboronic acids. Some difficulty was encountered in the preparation of arylnitromethanes, thus leading to the exploration of a cross-coupling strategy that proved more useful. A Barton-Zard pyrrole cyclocondensation reaction between 1,2-diaryl-1-nitroethenes and N-methoxy-N-methyl-2-isocyanoacetamide gave the corresponding pyrrole Weinreb amides, which were then converted into the desired 3-pyrrolin-2-ones in two steps. Overall, this method allowed for the construction of 3,4-diaryl-3-pyrrolin-2-ones with complete regiocontrol of the substituents with respect to the lactam carbonyl. The utility of this synthetic methodology was demonstrated by the preparation of eight unsymmetrical and symmetrical 3,4-diaryl-3-pyrrolin-2-ones including the N-H lactam analogue of the selective COX-II inhibitor, rofecoxib.
