Abstract
Abstract The combination of titanium-catalyzed anti-Markovnikov hydroamination of terminal alkynes with the Strecker reaction is used in the synthesis of unsymmetrical vicinal diamines via the one-pot synthesis of α-cyanoamines. This methodology is further applied to the efficient synthesis of imidazolidinones. An easy-to-use bis (amidate) titanium precatalyst permits efficient approaches to heterocyclic chemistry from terminal alkynes.
