α,β‐Unsaturated Gold(I) Carbenes by Tandem Cyclization and 1,5‐Alkoxy Migration of 1,6‐Enynes: Mechanisms and Applications

1,6‐Enynes bearing OR groups at the propargyl position generate α,β‐unsaturated gold(I)‐carbenes/ gold(I) stabilized allyl cations that can be trapped by alkenes to form cyclopropanes or 1,3‐diketones to give products of α‐alkylation. The best migrating group is p‐nitrophenyl ether, which leads to t...
