Gold catalysis: Switching the pathway of the furan-yne cyclization

Changing tracks: By the use of alkynyl ethers as directing elements, the furan-yne cyclization enters a new reaction pathway. Instead of phenols, tetracycles containing two heteroatoms and two new stereocenters are formed (see scheme).
