• progress to understand the exact mechanism of the reaction. Conclusion In conclusion, we have demonstrated that N-phenyl-3-substituted pyrazolones can be used for the intramolecular alpha-cyclisation of tertiary amines [33] for the synthesis of pyrazolinoquinolizine and 1,4-oxazinopyrazoline derivatives in
