title: Ugi/Himbert Arene/Allene Diels-Alder Cycloaddition to Synthesize Strained Polycyclic Skeleton.
abstract: The present work disclosed an efficient multicomponent reaction of isocyanide, allenic acid, aldehyde (ketone), and aniline. This protocol undergoes Ugi reaction followed by an intramolecular arene/allene Diels-Alder sequence, thus providing a rapid access to synthesize strained polycyclic skeletons.
