2,3-Bis[(trimethylsilyl)methyl]-1,3-butadiene as a versatile bis-nucleophilic reagent for the preparation of polyfunctional 1,3-diene derivatives

A new tandem C–C bond forming process has been developed, which utilises silyl-capped dienic bis-nucleophile 3 and various electrophiles under Lewis acid conditions; a short route for synthesis of functionalised 1,6-enynes has been proposed.
