On June 8, 2021, D’Hollander, Agathe C. A.; Romero, Eugenie; Vijayakumar, Kamsana; Le Houerou, Camille; Retailleau, Pascal; Dodd, Robert H.; Iorga, Bogdan I.; Cariou, Kevin published an article.Electric Literature of 141940-37-6 The title of the article was Base-Mediated Generation of Ketenimines from Ynamides: [3+2] Annulation with Azaallyl Anions. And the article contained the following:

Ynamides was underwent a [3+2] cycloaddition with 2-azaallyl anions, obtained from benzylimines under the basic conditions and heat was reported. This reaction between two highly reactive intermediates, both generated in situ from bench stable starting materials, gave access to various nitrogen-rich heterocycles. The reaction usually proceeded with excellent diastereoselectivity, in favor of the cis adduct. Deuteration experiments and DFT calculations helped rationalize the regio- and stereoselectivity of the process as well as the formation of side products. The experimental process involved the reaction of tert-Butyl (4-(trifluoromethyl)phenyl)carbamate(cas: 141940-37-6).Electric Literature of 141940-37-6
