Cascade Rearrangement of Furylcarbinols with Hydroxylamines: Practical Access to Densely Functionalized Cyclopentane Derivatives.

This article describes the aza-Piancatelli rearrangement with hydroxylamines to 4-aminocyclopentenones and subsequent transformations that highlight the versatility of the cyclopentene scaffold and the value of the hydroxylamine nucleophile in this transformation.
