Organocopper reagents from phenols: A new cobalt‐catalyzed arylsulfonate/copperexchange reaction allows the synthesis of highlyfunctionalizedarylcopperreagents from sulfonates bearing electron‐deficient substituents under mild conditions (25–45 °C, 1–6 h; see example). Sensitive functional groups, such as aldehydes, esters, and nitriles, are well‐tolerated.
Antitumoral compounds of Formula I, and pharmaceutically acceptable salts, derivatives, tautomers, prodrugs or stereoisomers thereof
useful as antitumour agents.
