Electroreductive Cobalt-Catalyzed Carboxylation: Cross-Electrophile Electrocoupling with Atmospheric CO2

The chemical use of CO2 as an inexpensive, nontoxic C1 synthon is of utmost topical interest in the context of carbon capture and utilization (CCU). We present the merger of cobalt catalysis and electrochemical synthesis for mild catalytic carb

Efficient Pd-Catalyzed Regio- and Stereoselective Carboxylation of Allylic Alcohols with Formic Acid

Formic acid is efficiently used as a C1 source to directly carboxylate allylic alcohols in the presence of a low loading of palladium catalyst and acetic anhydride as additive to afford β,γ-unsaturated carboxylic acids with excellent chemo-, regio-, and stereoselectivity. The reaction proceeds through a carbonylation process with in situ-generated carbon monoxide under mild conditions, avoiding the use of high-pressure gaseous CO. A bisphosphine ligand with a large bite angle (4,5-bis{diphenylphosphino}-9,9-dimethylxanthene, Xantphos) was found to be uniquely effective for this transformation. The regio- and stereoconvergence of this reaction is ascribed to the thermodynamically favored isomerization of the allylic electrophile in the presence of the palladium catalyst.

Method for preparing beta, gama-unsaturated carboxylic acid compound

The invention provides a method for preparing a beta, gamma-unsaturated carboxylic acid compound. The method comprises the steps of making an allylic alcohol compound of a formula 1 or a formula 2 react with formic acid in the presence of a palladium catalyst, a phosphorous ligand, acid anhydride and an organic solvent to obtain the beta, gamma-unsaturated carboxylic acid compound of a formula 3 or formula 4, wherein R1, R2 and R3 are defined in the description. Formic acid is utilized as a carboxylation reagent, and the beta, gamma-unsaturated carboxylic acid compound is low in price, safe, stable and low in toxicity; the yield is high, the operation is simple, and the economy is high; compared with an existing compounding method, the use of toxic gas carbon monoxide and/or an equivalent quantity of reactive metal reagents is avoided, and the method meets requirements for environment-friendly chemistry; in addition, the dose of catalysts is small, the reaction condition is mild, the reactant is high in conversion rate and product yield, and the method has a very good industrial prospect.

Synthesis and cardiovascular activity of phenylalkylamine derivatives. I. Potential specific bradycardic agents

A series of acyclic amide derivatives of N-(ω-aminoalkyl)-N-methylhomoveratrylamine was synthesized and evaluated for their bradycardic activity in isolated guinea pig right atria. Among these compounds, (E)-N-[3[N'-[2-(3,4-dimethoxyphenyl)ethyl]-N'-methy
