Direct arylation under catalysis of an oxime-derived palladacycle: Search for a phosphane-free method

A phosphane-free method for the direct arylation of benzothiazole by employing oxime-derived palladacycle 1 as a catalyst was developed. The new catalyst system can be used for 2-arylations by using aryl bromides and iodides. In addition, this method is especially suitable for the intramolecular direct coupling of bromo-and iodoamides, as well aschloroamides, to achieve a rapid synthesis of benzo[c]phenanthridine alkaloids. Direct arylation reactions under catalysis of an oxime-derived palladacycle were investigated. This phosphane-free method is applicable for the 2-arylation of benzothiazole and is especially suitable for the intramolecular direct coupling of bromo-and iodoamides, as well as chloroamides, to achieve rapid synthesis of benzo[c]phenanthridine alkaloids.
