A highly efficient protocol for the synthesis of isoquinolinediones by RhIII-catalyzed C-H activation/annulation/decarboxylation of N-tosylbenzamides with diazo compounds is reported. The switchable synthesis of isocoumarins was also achieved successfully via C-H activation/annulation with slight modification of the reaction conditions. Importantly, the synthetic utility of this new reaction was further demonstrated in an atom-economical and operationally convenient total synthesis of a TDP2 inhibitor derivative from commercially available starting materials.

An improved protocol to perform C-H radio-iodination is described. These new conditions allow rapid and clean formation of radio-iodinated N-acylsulfonamides using [125 I]NIS and catalytic amounts of palladium acetate and para-toluenesulfonic a

Regio- and stereoselective synthesis of (E)-3-arylmethyleneisoindolin-1-ones via Pd(II)/Cu(II)-catalyzed one-pot C-C/C-N bond forming sequence between amides and styrenes is reported. This method provides facile and rapid access to a diverse range of such compounds using readily available starting materials under mild aerobic conditions with good functional group tolerance and high selectivity and efficiency. Further elaboration of the products obtained from this process enabled very short and efficient syntheses of aristolactam and indoloisoquinolinone alkaloids.
