A novel synthesis of dihydropyrimidothienopyridazine derivatives

Aza-Wittig reaction of iminophosphorane 3, derived from 5- amino-3,4-diphenylthieno[2,3-c]piridazine-6-carboxaldehyde (1), with isocyanates, followed by intramolecular hetero conjugate addition annulation after addition of an amine, gives the functionaliz
