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.

lung adenocarcinoma cells. Herein, we report the synthesis of thiochondrilline C by N-terminal peptide extension, oxidative disulfide bond formation, and heterocycle installation as key steps. Antiproliferative activities for the prepared natural product and several derivatives against the NCI 60 cancer cell line panel are also described. Derivative 22 was identified as a moderately potent antiproliferative
