    a,b-Unsaturated Gold(I) Carbenes by Tandem Cyclization and 1,5- Alkoxy Migration of 1,6-Enynes: Mechanisms and Applications 

    Calleja, Pilar; Pablo, Óscar; Ranieri, Beatrice; Gaydou, Morgane; Pitaval, Anthony; Moreno, María; Raducan, Mihai; Echavarren, Antonio M. (2016-08-16)

    1,6-Enynes bearing OR groups at the propargyl position generate a,b-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 ...

    Ready Access to the Echinopines Skeleton via Gold(I)-Catalyzed Alkoxycyclizations of Enynes 

    Dorel, Ruth; Echavarren, Antonio M. (2016-08-16)

    The [3,5,5,7] tetracyclic skeleton of echinopines has been stereo- selectively accessed through a gold(I)-catalyzed alkoxycyclization of cyclopropyl- tethered 1,6-enynes. The key bicyclo[4.2.1]nonane core of the enyne ...
