Synthesis of exocyclic enamides via stereocontrolled allylic isomerization and 1,3-transposition
Khan,Marson,Porter
, p. 1753 - 1764 (2001)
In the presence of pyridinium para-toluenesulfonate (PPTS) an allylic alcohol moiety exocyclic to a lactam ring undergoes allylic isomerisation, or if the solvent is nucleophilic, 1,3-transposition can occur. All the rearrangements occurred with stereocon
Sequential 1,4- and 1,2-addition reactions to α,β-unsaturated N-acyliminium ions: A new strategy for the synthesis of spiro and bridged heterocycles

Novel bicyclic and tetracyclic spirocycles and tricyclic bridged heterocyclic systems can be readily prepared from sequential 1,4- and 1,2-addition reactions of latent bis-nucleophiles to α,β-unsaturated N-acyliminium ions.
