摘要：
The (3 + 2) cycloaddition/sulfur rearrangement reaction of donor-acceptor cyclopropanes bearing a single keto acceptor with indoline-2-thiones has been realized. Under the catalysis of Sn(OTf)(2), a series of functionalized 3-indolyl<bold>-</bold>4,5-dihydrothiophenes were synthesized with moderate to excellent yields.
