The first synthesis of 4-dendronized β-lactams using the standard Staudinger ketene-imine cyclization is described. Both ±-conjugated and Fre?chet's aromatic polyether dendrons having imine focal points were used as starting materials. Exclusive cisstereochemistry was observed for all the β-lactams prepared.
