Synthesis of 2-alkenylfurans <i>via</i> a Ag(<scp>i</scp>)-catalyzed tandem cyclization/cross-coupling reaction of enynones with iodonium ylides

Abstract

A silver(i)-catalyzed tandem cyclization/cross-coupling reaction of enynones with iodonium ylides to construct carbon-carbon double bonds has been developed. The strategy provides a novel method for the synthesis of 2-alkenylfurans. This is the first cross-coupling reaction between metal-carbene complexes and iodonium ylides.
