DIAZABICYCLOALKANES WITH NITROGEN ATOMS AT THE NODAL POSITIONS. 12. STEPHENS REARRANGEMENT IN SUBSTITUTED 1,4-DIAZABICYCLOOCTANES

Article abstract of DOI:10.1007/BF00506074

The ylides formed from phenacyl derivatives of substituted diazabicyclooctanes decompose to the initial base or give products of the Stephens rearrangement, leading to an expansion of the ring.The direction of the reaction is determined by the presence of
