Nazarov cyclisation of dienone-esters and tetrahydropyrones using trimethylsilyltriflate

Cyclopentenone esters have been synthesized via a Nazarov cyclisation of the corresponding α,α'-dienone esters or tetrahydro-γ-pyrone esters employing trimethylsilyltriflate at room temperature. The dienone esters were synthesised by a short two-step acylation-Knoevenagel sequence.
