Gold Catalysis: Switching the Pathway of the Furan-Yne Cyclization

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).
