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

Hashmi, A. Stephen K.,Rudolph, Matthias,Huck, Juergen,Frey, Wolfgang,Bats, Jan W.,Hamzic, Melissa

supporting information; experimental part, p. 5848 - 5852 (2009/12/06)

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).
