The cyclopentenone framework is found in a large number of natural products including aflatoxins and several prostaglandins and thus provides great opportunity for further development of currently used methodologies.  An Aza-Piancatelli rearrangement of furylcyclopropanes was developed.  The reactions were performed open to air with commercially available Dy(OTf)3.  Various aniline substrates were investigated to determine the scope of this rearrangement.  Cyclopropanes were found to be a good alternative in this rearrangement to promote ring opening rather than the creation of a charge and subsequently the loss of water.  I was successful in the development of a cyclopropane activated rearrangement.
