Aminocyclobutanes are high potential building blocks but have been underexplored. A one-step synthesis to access them from commercial starting materials was developed. Using these new donor-acceptor systems, a (4+2) annulation was conducted with indoles using silylium catalysis. When performed intramolecularly, the tetracyclic structure of either akuamma or malagasy alkaloids was obtained selectively
