Synthesis of Ortho-Arylated and Alkenylated Benzamides by Palladium-Catalyzed Denitrogenative Cross-Coupling Reactions of 1,2,3-Benzotriazin-4(3H)‑Ones with Organoboronic Acids

An efficient palladium-catalyzed denitrogenative Suzuki-Miyaura type cross-coupling of 1,2,3-benzotriazin-4(3H) ones with organoboronic acid is described. The reaction is compatible with various aryl and alkenyl boronic acids affording ortho-arylated and alkenylated...

Hydroxyl Group-Directed, Tartaric Acid-Catalyzed Synthesis of meta-Functionalized Aryl Ethers and Phenols through Domino Conjugate Addition/Aromatization of para-Quinols

A tartaric acid-catalyzed three-component reaction of para-quinols, organoboronic acids, and alcohols is reported, leading to meta-alkenylated aryl alkyl ether in a single step. Moreover, meta-functionalized phenols could also be obtained...

Mn(III)-Mediated Cascade Cyclization of 1-(Azidomethyl)-2-Isocyanoarenes with Organoboronic acids: Construction of Quinazoline Derivatives

A novel and efficient Mn(III)-mediated oxidative radical cascade reaction of 1-(azidomethyl)-2-isocyanoarenes with organoboronic acids is reported. The single electron oxidation of a commercially available organo boronic acid in presence of...

Palladium Catalyzed Desulfurative Coupling of Allyl Sulfides with Organoboronic Acids

A palladium catalytic desulfurative coupling of allylic sulfides with organoboronic acids under mild reaction conditions has been described. The reaction exhibits high chemoselectvity and good functional group torerance, allowing the...
