The gold(I)-catalyzed hydroarylation of cyclohexa-1,3-dienes bearing an aryl group and a gem-diester in the tether proceeds in a 1,4-addition manner and in a diastereoselective fashion to afford perhydrophenanthrene rings. The reaction proceeded via attack of the aryl group onto the gold-activated cyclic dienes followed by rearomatization and protodeauration to generate perhydrophenanthrenes in good
链中带有芳基和宝石-二酯的环己-1,3-二烯的金(I)催化加氢芳基化反应以1,4-加成方式和非对映选择性方式进行,从而得到全氢菲环。该反应通过芳基攻击金激活的环状二烯上进行,然后重新芳构化和原型脱氢,以高收率生成过氢菲。该加氢芳基化反应可用于由芳基连接的环庚二烯和金(I)催化剂合成全氢环庚[ a ]萘。
