Potassium benzofuran-2-yltrifluoroborate (cas: 929626-27-7) belongs to benzofurans derivatives. Benzofurans are only weakly aromatic in nature and they are cleaved by many oxidative and reductive conditions. Introduction of benzofurans in organic synthesis, particularly drug synthesis, involves generally the use of their metalated species as nucleophiles in addition reactions or in metal-catalysed cross-coupling reactions.Product Details of 929626-27-7

Organocatalyzed Asymmetric Conjugate Addition of Heteroaryl and Aryl Trifluoroborates: a Synthetic Strategy for Discoipyrrole D was written by Shih, Jiun-Le;Nguyen, Thien S.;May, Jeremy A.. And the article was included in Angewandte Chemie, International Edition in 2015.Product Details of 929626-27-7 This article mentions the following:

Bis-heteroaryl or bis-aryl stereocenters were formed by an organocatalytic enantioselective conjugate addition using the resp. trifluoroborate salts as nucleophiles. Control studies suggested that fluoride dissociation was necessary in the anhydrous conditions. This strategy was applied to the synthesis of a protected form of discoipyrrole D, an inhibitor of BR5 fibroblast migration. In the experiment, the researchers used many compounds, for example, Potassium benzofuran-2-yltrifluoroborate (cas: 929626-27-7Product Details of 929626-27-7).
