摘要
A new approach to benzo-annelated delta-sultams containing an aryl-nitrogen bond is described. The method, which involves the intramolecular Michael cyclization of tert-butyl ortho-[N-(methoxycarbonylmethyl) sulfonylamino] cinnamates, allows the synthesis of secondary sultams as well as their tertiary analogues and bridged tricyclic derivatives efficiently and diastereoselectively.
