. It describes the addition of lithiated ethoxyacetylenes to
ketones
In organic chemistry, a ketone is a functional group with the structure R–C(=O)–R', where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group –C(=O)– (which contains a carbon-oxygen double bon ...
to give propargyl alcohols, which can undergo further reaction to form α,β-unsaturated aldehydes, or esters. There is also a variation of this reaction called the Isler modification, where the acetylide anion is generated in situ from β-chlorovinyl ether using
