The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: Ethyl oxazole-5-carboxylate(SMILESS: O=C(C1=CN=CO1)OCC,cas:118994-89-1) is researched.Safety of 4-Bromo-1-methyl-2-nitro-1H-imidazole. The article 《Visible-Light Photoredox-Catalyzed Decarboxylative Alkylation of Heteroarenes Using Carboxylic Acids with Hydrogen Release》 in relation to this compound, is published in Organic Letters. Let’s take a look at the latest research on this compound (cas:118994-89-1).
Herein, we have developed visible-light photoredox-catalyzed decarboxylating carboxylic acids for alkylation of heteroarenes under mild conditions. The transformation occurred smoothly without the requirement of stoichiometric oxidants in the presence of 0.3 equiv of base, which benefited from the release of hydrogen (H2) and carbon dioxide (CO2). Various substrates and functional groups were tolerated. Primary mechanistic studies suggest that an oxidative quenching pathway and a reductive quenching pathway are both possible in the catalytic cycle.
This literature about this compound(118994-89-1)Reference of Ethyl oxazole-5-carboxylatehas given us a lot of inspiration, and I hope that the research on this compound(Ethyl oxazole-5-carboxylate) can be further advanced. Maybe we can get more compounds in a similar way.
