Abstract
The reaction of aryl iodides with alkyl 4-hydroxy-2-alkynoates in the presence of formic acid, tri-n-butylamine and a palladium (II) catalyst provides a convenient route to functionalized substituted butenolides through a one pot hydroarylation/cyclization reaction. In the presence of formic acid, tri-n-butylamine and a palladium (II) catalyst, alkyl 4-hydroxy-2- alkynoates undergo a one pot hydrogenation/cyclization reaction to the butenolide ring. ...
