Dynamic Carbon Isotope Exchange of Pharmaceuticals with Labeled CO2

A copper-catalyzed procedure enabling dynamic carbon isotope exchange is described. Utilizing the universal precursor [14C]CO2, this protocol allows to insert, in one single step, the desired carbon tag into carboxylic acids with no need of structural modifications. Reducing synthetic costs and limiting the generation of radioactive waste, this procedure will facilitate the access to carboxylic acids containing drugs and accelerate early 14C-based ADME studies supporting drug development.

Catalytic syntheses of N-heterocyclic ynones and ynediones by in situ activation of carboxylic acids with oxalyl chloride

Breaking the bottleneck: alpha-Keto carboxylic acids and N-heterocyclic carboxylic acids are activated in situ with oxalyl chloride then catalytically alkynylated to give ynediones and N-heterocyclic ynones efficiently in a one-pot fashion. 5-Acylpyrazoles and 2-phenylaminopyrimidines, potentially interesting for pharmaceutical applications, are readily synthesized in concise one-pot, three-component syntheses.

Some tips on 16136-58-6

As the paragraph descriping shows that 16136-58-6 is playing an increasingly important role.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.16136-58-6,1-Methyl-1H-indole-2-carboxylic acid,as a common compound, the synthetic route is as follows.

To a 0¡ã C. solution of ethyl cis-2-amino-1-cyclohexanecarboxylate HBr salt (9.03 g, 35.8 mmol), 1-methylindole-2-carboxylic acid (6.18 g, 35.3 mmol), HOBT (5.45 g, 40.3 mmol), and EDCI.HCl (7.45 g, 38.9 mmol) in 70 mL of anhydrous DMF was added N-methylmorpholine (7.8 mL, 71 mmol). The reaction mixture was stirred for 24 h at room temperature. The reaction mixture was cooled in an ice bath and treated with 140 mL of water. 140 mL of ethyl acetate was added to the resulting yellow suspension and stirred until the solids dissolved. An additional 140 mL of ethyl acetate was added and the organic layer was separated. The organic layer was washed with two 280 mL portions of 0.5 M HCl, 280 mL of brine, then dried over sodium sulfate, filtered and concentrated to give a crude yellow solid. Purification by column chromatography (30:70, ethyl acetate:hexanes) gave 10.9 g of the product as a pale green-tinted solid. Yield: 90percent, MS: 329 (M+H+), mp=98.1-99.0¡ã C.
