Addition of lithium metal to but-1-en-3-ynes. Synthesis and epoxidation of 1,4-bis(trimethylsilyl)buta-1,2-dienes

But-1-en-3-ynes react with lithium and chlorotrimethylsilane in THF to give 1,4-bis(trimethylsilyl)buta-2,3dienes. Epoxidation of these allenes leads to oxyallyl species which are trapped by nucleophilic reagents to give 1,4-bis(trimethylsilyl)butan-3-ol-2-one derivatives.
