A Lewis acid mediated rearrangement of 1-(trimethylsilyl)prop-2-ynyl trimethylsilyl ethers to 2-trimethylsilyl enones
Abstract
Treatment of 1-(trimethylsilyl)prop-2-ynyl trimethylsily ethers methylaluminium dichloride leads to the formation of the 3-metallated 2-(trimethylsilyl)enones, which, on quenching with water, afford the corresponding 2-(trimethylsilyl)enones in good yields.
