Reaktionsschritte

2-(Trimethylsiloxy)-1,3-butadiene (900 mg, 6.33 mmol) and ethyl cyclopropylideneacetate (2195 mg, 17.40 mmol) were combined in toluene (3 ml) and heated to 130° C. for 14 h. The mixture was then allowed to cool to room temperature and concentrated in vacuo to yield ethyl 7-[(trimethylsilyl)oxy]spiro[2.5]oct-6-ene-4-carboxylate that was used without further purification in the subsequent reaction.
