Tandem oxidative radical fragmentation–rearrangement of 2-amino-1,3-benzylidene acetals : a short entry to densely functionalised fully differentiated oxazolidinones

The discovery of a novel tandem fragmentation–rearrangement process from N-Boc-protected benzylidene acetals is reported. The reaction proceeds via free-radical initiation and terminates through a 5-exo-tet ionic fragmentation process leading to biologically useful, densely functionalised oxazolidinones.
