Xu, Yan;Qi, Xiaotian;Zheng, Pengfei;Berti, Carlo C.;Liu, Peng;Dong, Guangbin research published 《 Deacylative transformations of ketones via aromatization-promoted C-C bond activation》, the research content is summarized as follows. Carbon-hydrogen (C-H) and carbon-carbon (C-C) bonds are the main constituents of organic matter. Recent advances in C-H functionalization technol. have vastly expanded our toolbox for organic synthesis. By contrast, C-C activation methods that enable editing of the mol. skeleton remain limited. Several methods have been proposed for catalytic C-C activation, particularly with ketone substrates, that are typically promoted by using either ring-strain release as a thermodn. driving force or directing groups to control the reaction outcome. Although effective, these strategies require substrates that contain highly strained ketones or a preinstalled directing group, or are limited to more specialist substrate classes. Here we report a general C-C activation mode driven by aromatization of a pre-aromatic intermediate formed in situ. This reaction is suitable for various ketone substrates, is catalyzed by an iridium/phosphine combination and is promoted by a hydrazine reagent and 1,3-dienes. Specifically, the acyl group is removed from the ketone and transformed to a pyrazole, and the resulting alkyl fragment undergoes various transformations. These include the deacetylation of Me ketones, carbenoid-free formal homologation of aliphatic linear ketones and deconstructive pyrazole synthesis from cyclic ketones. Given that ketones are prevalent in feedstock chems., natural products and pharmaceuticals, these transformations could offer strategic bond disconnections in the synthesis of complex bioactive mols.
