Beschreibung

Anwendung

Propargyl alcohol has been used as a key starting material in the [4+2] cycloisomerization mediated synthesis of various phthalide derivatives.
It can also be used to synthesize:

• A variety of regioselective furan-3-carboxamides by reacting with 3-oxo amides using Ag₂CO₃ as a promoter.
• β-oxopropyl esters by reacting with carboxylic acids in the presence of (arene) (phosphine)ruthenium(II) complex as a catalyst.
