On October 1, 2021, Faltracco, Matteo; Damian, Matteo; Ruijter, Eelco published an article.Category: indole-building-block The title of the article was Synthesis of Carbazoles and Dihydrocarbazoles by a Divergent Cascade Reaction of Donor-Acceptor Cyclopropanes. And the article contained the following:
An alkylation/olefination cascade of indolecarboxaldehydes and phosphonate-functionalized donor-acceptor cyclopropanes affords functionalized dihydrocarbazoles and cyclohepta[cd]indoles in formal [3 + 3] and [4 + 3]-cycloadditions A minor modification to the reaction conditions also allowed access to the fully aromatic heterocyclic scaffolds by thermal loss of an electron-rich aryl moiety. The experimental process involved the reaction of 1,5-Dimethyl-1H-indole-2-carbaldehyde(cas: 883526-76-9).Category: indole-building-block
