SDS of cas: 651780-02-8. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: tert-Butyl 5-bromo-1H-indazole-1-carboxylate, is researched, Molecular C12H13BrN2O2, CAS is 651780-02-8, about The Suzuki reaction applied to the synthesis of novel pyrrolyl and thiophenyl indazoles. Author is Migliorini, Antonella; Oliviero, Chiara; Gasperi, Tecla; Loreto, Maria Antonietta.
The paper describes the Suzuki cross-coupling of a variety of N and C-3 substituted 5-bromoindazoles with N-Boc-2-pyrrole- and 2-thiopheneboronic acids. The reactions, performed in the presence of K2CO3, dimethoxyethane, and Pd(dppf)Cl2 as catalyst, gave the corresponding adducts in good yields. The methodol. allows the facile production of indazole-based heteroaryl compounds, a unique architectural motif that is ubiquitous in biol. active mols.
