[Thermolyses of N-allylides and N-vinylimino ylides: syntheses of mesomeric betaines involving back-donated 1,6-cyclization].
This review summarizes our studies on the development of the syntheses of mesomeric betaines by thermolysis of N-allylides and N-vinylimino ylides involving back-donated 1,6-cyclization. Furthermore interesting syntheses of heteropolycycles, indolizinoquinolizines via one step reaction are also reviewed.
