2-Vinyl-N,N-dialkylanilines react thermally in polar solvents and/or in the presence of Lewis acids via or hydrogen transfer followed by C-C bond formation to give heterotricyclic compounds.The reaction depends on the type of N,N-dialkylamino
1-Pyrrolidin-1-ylbuta-1,3-dienes as Potential 1,5-Dipoles; Synthesis of Pyrrolizines

Tautomerization of 1-pyrrolidin-1-ylbuta-1,3-dienes and (hetero)aromatic compounds formally containing this moiety, to the corresponding 1,5-dipoles by a concerted hydrogen shift is followed by a 1,5-electrocyclization to give pyrrolizine derivative
