Heterocyclically Bridged Tricyclic β-Lactames: A Simple Synthesis of 1,2,2a,8a-Tetrahydro-3-oxa-1-aza-cyclobuta[b]naphthalen-2-ones

Article abstract of DOI:10.1007/BF00807565

The tricylic 3,4-bridged β-lactames 7 and 8 containing a hetero atom as 3-substituent of the azetidin-2-one ring were synthesized by intramolecular radical cyclization using cis-substituted 3-(2-bromo-aryloxy)-azetidine-2-ones 6 as precursors. These precu
