Abstract

Several kinds of 1-arylazetidin-2-ones were treated with trifluoroacetic acid to give 1,2,3,4-tetrahydroquinolin-4-ones. In the case of 1-arylazetidin-2-ones possessing a substituent at the 3-position, the rearrangement occurred at both ortho- and para-positions to the substituent located at the 3-position.
