Bien, Jeffrey published the artcileThe First Kilogram Synthesis of Beclabuvir, an HCV NS5B Polymerase Inhibitor, Recommanded Product: 3-Cyclohexyl-1H-indole-6-carboxylic acid, the main research area is beclabuvir diastereoselective enantioselective kilogram scale preparation; stereoselective rhodium catalyzed cyclopropanation alkylation key step preparation beclabuvir; palladium catalyzed intramol arylation key step preparation beclabuvir.
A process for the multikilogram-scale preparation of the hepatitis B NS5B RNA polymerase inhibitor beclabuvir I was developed using a diastereoselective and enantioselective cyclopropanation using the Davies catalyst Rh2(S-DOSP)4, an alkylation to merge indole and cyclopropane fragments, and an intramol. palladium-catalyzed arylation as the key steps. I·HCl was prepared in 12 linear steps with 5 isolations in an overall yield of 8%.
Organic Process Research & Development published new progress about Alkylation. 494799-17-6 belongs to class indole-building-block, name is 3-Cyclohexyl-1H-indole-6-carboxylic acid, and the molecular formula is C15H17NO2, Recommanded Product: 3-Cyclohexyl-1H-indole-6-carboxylic acid.
