stereoselective Ir(I)-catalyzed isomerization of 1,1-disubstituted and trisubstituted allylic ethers and in situ [3,3] sigmatropicrearrangement of the resulting allyl vinyl ethers provide for the highly stereoselective construction of quaternary carbon stereocenters. The olefin isomerization-Claisen rearrangement (ICR) sequence allows adjacent quaternary-tertiary stereocenter relationships to be established with
