摘要：
An intramolecular [2+2] cycloaddition using N-sulfonyl substituted ynamides tethered to an enone motif is described here. This thermally driven [2+2] cycloaddition manifold can be catalyzed effectively using AgNTf2, and represents the first examples of an intramolecular Ficini reaction. Published by Elsevier Ltd.
