SYNTHESIS OF AZA-β-LACTAMS BY RHODIUM CARBENOID MEDIATED CYCLISATION
Moody, Christopher J.,Pearson, Christopher J.,Lawton, Geoffrey
, p. 3171 - 3172 (1985)
Treatment of the diazo-compounds (3), obtained in two steps from readily available hydrazine derivatives (1), with a catalytic amount of rhodium (II) acetate in benzene gives the aza-β-lactams (4) in high yield.
