摘要：

The gold(I)-catalyzed intramolecular hydroarylation of methylenecyclopropanes containing aryl propargyl ethers proceeded smoothly to give 2H-chromene derivatives in good to excellent yields under mild conditions. Furthermore, in the presence of IPrAuSbF6, these 2H-chromene derivatives containing a methylenecyclopropane could undergo ring enlargement to give the corresponding cyclobutenes.
