Catalytic asymmetric inverse electron demand Diels–Alder reaction of fulvenes with azoalkenes†
Abstract
An unprecedented copper(I)-catalyzed asymmetric inverse electron demand Diels–Alder reaction of azoalkenes with fulvenes is reported. This methodology offers a directed entry to synthesize bicyclic tetrapyridazine derivatives in good yield with exclusive regioselectivity and excellent stereoselectivity.
