ChemInform Abstract: Ynol Ethers: Synthesis and Reactivity

Ynol ethers are highly valuable substrates offering a wide range of reactivity. These highly electron-rich heterosubstitued alkynes can be of great synthetic potential. In this mini-review, the different methods for the synthesis of ynol ethers are first presented, divided in three main approaches involving a β-elimination, a carbene rearrangement and a direct oxidation of an alkyne. Their reactivity is then summarized underlying their synthetic utility. This non-exhaustive review aims at presenting the intrinsic reactivity of these compounds, still underexploited in synthesis.
