Intermolecular annulation of enynes and propargyl esters to selectively produce styrenes or fluorenes is reported. The divergent arene syntheses involve a Au-catalyzed, two-pot, multistep process proceeding by cis-diastereoselective cyclopropanation, cycloisomerization, and, finally, annulation or elimination.
据报道,烯炔与炔丙基酯的分子间环化反应可选择性地生成苯乙烯或芴。这种不同的芳烃合成涉及一个金催化的两步多步过程,该过程通过顺式非对映选择性环丙烷化、环异构化,最后进行环化或消除反应来进行。
