The oxidative coupling of β-carbonyl imines and allyltrimethylsilane with CTAN were investigated in CH3CN and CH2Cl 2. In CH3CN allylation products were obtained predominantly, while in CH2Cl2, dihydropyrrole products were obtained exclusively. Solvent-assisted nucleophilic cleavage of the intermediate β-silyl cation is proposed to play a role in the solvent-dependent chemoselectivity.

4-Hydroxy-2-(1H)-pyridones 3 can be obtained in excellent yields from azomethines 1 with trichlorophenylmalonates 2.The variation of the substituents in position 1,3,5 or 6, respectively is possible over a wide range.In this manner the 5,6-fused-pyridones
