Ruthenium(II)-catalyzed C-H functionalization of N-arylhydantoins is herein described. The biologically relevant hydantoin (imidazolidinedione) heterocycle functions as a weakly coordinating directing group in a C-H alkenylation reaction. The reaction gave a wide scope of 23 examples with yields up to 94% in the green solvent 2-MeTHF. Functionalization of(More)
We have reviewed the surgical treatment of 12 consecutive patients with advanced carcinoma of the parotid gland at this hospital. Ten patients received immediate preoperative radiotherapy to a mean total dose (TD) of 4000 cGy (rad), range 2600-6500 cGy. Two patients with recurrent carcinoma had previously been treated with local radiotherapy (TD 6500 cGy)(More)
