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. hydroamination - titanium - amines - heterocycles - tandem reactions
