An unprecedented gold(i)-catalyzed cyclization of cyclopropylidene-tethered propargylic alcohols via a 6-endo-dig enyne cyclization followed by a ring-opening of cyclopropane and nucleophilic closure reaction to construct naphtho[2,3-c]pyrans was developed. This transformation represents a highly efficient method for the synthesis of polycyclic compounds in one-pot, and two new rings are formed in an atom economic manner.
发展了一种前所未有的金(i)催化环化反应，通过 6-endo-dig 烯炔环化反应和随后的环丙烷开环、亲核闭环反应，将环丙叉基丙炔醇环化，构建萘并[2,3-c]吡喃。这种转化代表了一种在一锅法中高效合成多环化合物的方法，以原子经济性的方式形成两个新环。
