Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 174775-48-5, Name is Ethyl 5-aminobenzofuran-2-carboxylate, molecular formula is C11H11NO3, belongs to benzofurans compound, is a common compound. In a patnet, author is Reddy, Raju Jannapu, once mentioned the new application about 174775-48-5, Application In Synthesis of Ethyl 5-aminobenzofuran-2-carboxylate.
Pd-Catalyzed Annulation of beta-Iodovinyl Sulfones with 2-Halophenols: A General Route for the Synthesis of 3-Sulfonyl Benzofuran Derivatives
The palladium-catalyzed annulation between beta-iodovinyl sulfones and 2-halophenols or 1-bromo-2-naphthol or 2-bromo-3-pyridinol is presented. The annulation process involving oxa-Michael addition-elimination and intramolecular Heck reaction leading to form 2,3-disubstituted benzofurans (aryl benzofuryl sulfones) in good to high yields. The regioselective tandem construction of C-O and C-C bonds has been achieved with a variety of substitution patterns. Moreover, the tandem process is reliable at gram-scale reactions and a plausible mechanism is also proposed.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 174775-48-5. The above is the message from the blog manager. Application In Synthesis of Ethyl 5-aminobenzofuran-2-carboxylate.
