molecule synthesis. However, only a limited amount of examples are known for most functional groups. Herein, we describe such an unusual process of oxetanes. In the presence of In(OTf)3 as catalyst, oxetane‐tethered anilines reacted unexpectedly to form 1,2‐dihydroquinolines. This process not only provides expedient access to dihydroquinolines, but also represents a new reaction of oxetane. Mechanistically

An efficient one-pot procedure for the four-step preparation of 7-hydroxyquinoline (1) from 3-N-tosylaminophenol (4) in 60% isolated yield, that reduces the risk of exposure to acrolein (2), is described.
