Method for preparing aryl primary amide by adopting metal-catalyzed one-pot method

The invention discloses a method for synthesizing aryl primary amide by adopting a metal-catalyzed one-pot method. The method comprises the steps of: taking aryl bromidess as raw materials, allowing the aryl bromidess to react with a cyanide source under the action of a palladium catalyst, substituting bromine on an aromatic ring with cyano to obtain cyano aromatic hydrocarbon, directly adding anaqueous solution of alkali into the reaction solution without aftertreatment, and carrying out hydrolysis reaction to obtain aryl primary amide. Compared with the prior art, the method for preparing aryl primary amide from the aryl bromides has the advantages of the short synthesis route, fewer reaction steps, simple operation, mild conditions, the high conversion rate, low toxicity and industrialproduction potential.

C?H Cyanation of 6-Ring N-Containing Heteroaromatics

Heteroaromatic nitriles are important compounds in drug discovery, both for their prevalence in the clinic and due to the diverse range of transformations they can undergo. As such, efficient and reliable methods to access them have the potential for far-reaching impact across synthetic chemistry and the biomedical sciences. Herein, we report an approach to heteroaromatic C?H cyanation through triflic anhydride activation, nucleophilic addition of cyanide, followed by elimination of trifluoromethanesulfinate to regenerate the cyanated heteroaromatic ring. This one-pot protocol is simple to perform, is applicable to a broad range of decorated 6-ring N-containing heterocycles, and has been shown to be suitable for late-stage functionalization of complex drug-like architectures.

A Bifunctional Reagent Designed for the Mild, Nucleophilic Functionalization of Pyridines

Herein is reported the design and application of a reagent for the direct functionalization of pyridines. These reactions occur under mild conditions and exhibit broad functional group tolerance, enabling the late-stage functionalization of drug-like molecules. The reagent can be easily prepared on large scale from inexpensive reagents, and reacts in the title reaction with acetonitrile, sodium chloride, and sodium methanesulfonate as the sole byproducts. Although this Communication focuses primarily on reactions with cyanide as nucleophile, preliminary experiments with other nucleophiles foreshadow the broad reaching synthetic utility of this approach.

A stereoselective process for the preparation of novel phosphonoalkylphosphinates

We have devised both a contiguous and a stepwise strategy for the synthesis of the pyridylaminomethane-based class of phosphonoalkylphosphinates (PAPs) that form via the intermediacy of the phosphonoethoxyaminomethane XIa. The PAPs result from condensation of picolines and phosphonoacetals in high chemoselective yield. Following reduction of aminopyridine IIIb, the unprecedented Pt(0)-catalyzed epimerization of the chelated amidine [(hydroxy)methylphosphinyl]-[(3-methyl-2-piperidinyl-idene)amino]methylphosphonic acid (IIIa) yielded a single racemic pair of PAPs (IIIc). The epimerization was found to occur more slowly than amidine formation itself.
