资源简介：
The stereoselective anti SN2‘ attack of NaN3 to 3-alkenyl-3-bromo-azetidin-2-ones gave a mixture of diastereomeric azides in fast equilibrium.
The [3,3]-sigmatropic rearrangement of allylic azides occurred with complete stereocontrol, allowing the equilibrium to be directed preferentially
toward the (E)- or (Z)-isomer, useful precursors of 3(2‘-amino)-β-lactams.
